But we can only see that part of shadow of the object which above the surface of water i.e in air and the part which is completely immersed in water. We cannot see that part in shadow which is present exactly at the interface of both media (air and water).The shadow appears to be break as no shadow has been formed at the interface. Why?

Whereas, we find integration by calculating the area under the curve associated........ Differentiation is also known as the reverse process of Integration........ ..d/dx(x*2) = 2x,...... Integration (2x dx) = x*2...... similarly, d/dx(sin x) = cosx. Integration (cosx dx) = sin x ......

Maybe minor difference but it is there so g is different for every object (minor difference) so each must take different time to reach earth As g has minor difference for them t must also differs minorly but difference is there.🤔

The particle A is clamped to a fixed point in the lab and the particle B which has a mass m, is released from rest with an initial separation r0 from A. Find the charge in the potential energy of the two particle system as the separation increases to a large value. What will be the speed of the particle B in this situation?

@bidishanag4198
Жыл бұрын
the current that is created due to changing electric field,for example in charging of a capacitor when its not completely charged to its capacity there is a constant change in the charge getting stored and hence the electric field changes and the change in electric field causes a varying magnetic field which causes displacement current.This is in support of the fact that changing electric fields cause magnetic fields.In the space between the capacitor the amperes circuital law did not provide any magnetic field because the current there was 0.To overcome the inconsistency of no magnetic field being there a current was established between the plates of the capacitor.

The deflection in galvanometer just indicates that a current is passing through it. It can also show what's the direction of current in the circuit.

No force is acting on that stone and the stone isn't acting against any forces, yet it is still there. Even though there is a height, no work was ever done on it to bring it to that state of position. Will the stone have potential energy? Will we take the height as 0 or not? Please solve the doubt Sir. Thank you

Yes , because by Einstein theoram energy is directly proportional to to the mass and the stone is kept on the top a hill it means it has a some height of energy which we called potential energy but in case if we falling freely this stone from this height then it comes in some motion having some moving velocity and in this phenomenon potential energy is decreasing and by come into the motion having velocity it will be covert in to kinetic energy because height will decrease

Sir my name is Siddhant Jani , I have a very big doubt , however nobody answers my doubts. I study in class 10 and my doubt is of the chapter electricity. Sir we should assume a circut with battery and a wire. So sir if the resistence of the wire is infinite then no current can pass through the wires.Now sir as we go on decreasing the resistence of the wire( By changing the wires) we find that more current can flow to the circut. And as the resistence of the wire starts to approach towards zero , moreand more current can pass through the wire. Now sir in a video you had cleared the doubt of a student( current with no potential difference) where u had stated that the wires are so thick that we assume the resistence as zero(In that case sir actually the potential difference was also not zero , since the resistence of the wire was not actually zero) due to which current flowed. Now sir back to my doubt IF THE WIRE ACTUALLY HAD THE RESISTENCE AS ZERO THEN THAT WOULD MEAN LITERALLY NO POTENTIAL DIFFERENCE ACROSS BATTERY AND HENCE ELECTRIC CURRENT WOULD NOT BE ABLE TO FLOW ( NO DIFFERENCE OF ENERGY OF ELECTRONS). SO SIR WHEN THE WIRES HAVE POTENTIAL DIFFERENCE OF ZERO AND INFINITE SAME PROPERTIES ARE SHOWN( NO CURRENT IS ALLOWED TO FLOW THROUGH THEM). BUT SIR AS WE INCREASE AND DECREASE THE RESISTENCE OF THE WIRES(POTENTIAL DIFFERENCE IS DIRECTLY PROPORTIONAL TO THE RESISTENCE) WE GET DIFFERENT PHYSICAL PROPERTIES OF THE WIRES. SO SIR AT 2 EXTREME CASES WE GET THE SAME RESULTS??? CAN U PLS EXPLAIN THIS . ALSO SIR I HAD ANOTHER DOUBT THAT IN SUPERCONDUCTORS THE THE RESISTENCE IS ACTUALLY ZERO , BUT STILL ELECTRIC CURRENT FLOWS THROUGH THEM . SIR IF RESISTENCE IS ZERO THEN THE P.D IS ALSO ZERO SO NO DIFFERENCE IN ENERGY OF ELECTRONS < BUT STILL ELECTRIC CURRENT FLOWS THROUGH SUPERCONDUCTORS. HOW?? SIR I THINK THE ANSWER TO THIS QUESTION WILL CLEAR MY PREVIOUS QUESTION. SIR IF POSSIBLE PLS CLEAR MY DOUBT SINCE NO ONE CLEARS MY DOUBTS.

@@jsaifi7402 But in superconductors the resistance is not actually zero. Its approaching towards zero. So when the resistance of a wire gradually tends towards zero , there is no energy required to move a charge. But if the resistance actually becomes 0 then how can current flow. because v/i = r and similarly v/r = i. Now as the resistance decreases the current flowing increases, but the current only increases till when the resistance is approaching towards 0.However this does not happen when the resistance is actually 0. you should know that when u divide any number with 0 u dont get infinity. So that is my question. See there is a difference in saying the resistance is 0 and is approaching towards 0. Also u are already assuming that current flows when the resistance is actually 0 . See when the resistance is actually 0, flowing of current is not possible only. See when u divide by 0 u dont get an answer. (v/r = i)Similarly when the resistance is actually 0(v/0) , how can current flow in the first place. and when the resistance is infinity then also no current can flow. So there is a similarity in characteristics of a wire when the resistance is 0 and when its infinity. So at 2 extreme cases we get the same results???Pls explain this

@@jsaifi7402 Lets assume that the resistance of a wire is 0. See you have also stated that v/0 = undefined. So when the resistance is 0 (v/0 = i). Now according to you there will be current flowing through the wire if the resistance is 0. If we assume that some current flows through the wire then this equation (v/0 = i) cannot be satisfied. But u might argue that v(potential difference) would be zero bec i considered the resistance as 0. ( and v/i = r)(you are right when the resistance is 0 the potential difference would also be 0)That would give us 0/0 = i.(v/r = i)( v = 0 , i = 0) Now logically 0/0 can actually be anything.( if 0/0 = 1 then 1 x 0 = 0, 0/0 = 2, 2x 0 = 0) , so 0/0 can actually be anything. This actually means that when current flows through a wire with 0 resistance the current is not defined. So the current flowing through the wire can be 1ampere , 2 ampere 3 ampere , but can also be 0 ampere. So lets consider one case when the resistance of a wire is 0 ohms , and the current flowing is 0 amperes( I am not saying that the current will always be 0 when the resistance is 0)(But there will be 1 case in which the current flowing through the wire will be 0). Also when the resistance is infinite the current flowing through the wire would be 0. So there is a similarity in characteristics of a wire when the resistance is 0 and when its infinity.So at 2 extreme cases we get the same results??? Now you might argue that 0/0 is undefined and not any number. So i would like to ask YOU what is the current when the resistance of a wire is actually 0. Because when u say that the current is undefined what do you actually mean. It means that the current is not defined, meaning the current could be anything and it does not have a definite or fixed value. * Also i would like to say one more thing . When the potential difference across 2 ends is 0 CURRENT CANNOT FLOW BETWEEN 2 ENDS. YOU MIGHT ARGUE THAT THIS ISNT TRUE WHEN THE RESISTANCE ACROSS 2 ENDS IS 0. BUT TO THAT I WOULD REPLY THAT WHEN THE POTENTIAL DIFFERENCE ACROSS 2 ENDS IS 0 THE RESISTANCE ACROSS THE 2 ENDS IS ALSO ACTUALLY (ALWAYS) 0. SO BY SAYING THAT ELECTRIC CURRENT WOULD FLOW WHEN THE RESISTANCE ACROSS 2 ENDS IS 0 YOU ARE SAYING THAT WHEN THE POTENTIAL DIFFERENCE ACROSS 2 ENDS IS 0 ,CURRENT WOULD ALWAYS FLOW .( WHEN THE POTENTIAL DIFFERENCE IS ALWAYS 0 THE RESISTANCE ACROSS 2 ENDS WOULD ALSO ALWAYS BE 0) BUT WE KNOW THAT CURRENT DOES NOT FLOW WHEN THE POTENTIAL DIFFERENCE ACROSS 2 ENDS IS 0.OK FINE LETS CONSIDER 1 CASE (ONLY 1) WHEN THE POTENTIAL DIFFERENCE ACROSS 2 ENDS IS 0 AND HENCE THE CURRENT DOES NOT FLOW. IN THIS CASE THE RESISTANCE WOULD ALSO BE ZERO(V/I = R). SO WE HAVE PROVED THAT IN 1 CASE WHEN THE RESISTANCE IS 0 , CURRENT DOES NOT FLOW. AND NOW AGAIN I AM ASKING THE SAME QUESTION

@@jsaifi7402 I understand what you are trying to say , and you are not completely wrong.However I am not fully convinced by your 3rd point. See you yourself have proved that 0/0 can be anything. You said that there was no battery and a resistor of 10ohms. Here the current would obviously be 0. So v/i = r. here v=0 , i = 0, r is 10ohms , so 0/0 = 10. Similarly here the resistor could have any resistance. Now we can also take v/r = i , if the resistance is 0 , the potential difference is 0 , then the current can be anything. Even 0. Like in the previous case the resistance could be anything. *BY THE WAY THE REFRACTIVE INDEX OF GLASS WHEN A RAY IS PASSED NORMALLY , IS NOT 0/0 , BUT ITS 1 ( sini/sinr) , sin90/sin90 = 1/1= 1. HERE ACTUALLY IN 1 CASE WE GET A DIFFERENT RESULT THAN OTHER CASES. IN ALL REST CASES THE REFRACTIVE INDEX OF A GLASS SLAB WOULD BE 1.5. BUT IN THE CASE WE ARE TALKING NOW , THE CURRENT PASSED THROUGH THE WIRE COULD BE ANYTHING. SEE YOU YOURSELF HAVE ALSO PROVED THAT 0/0 CAN BE ANYTHING. -ALSO LAST BUT NOT THE LEAST , YOU SAID THAT R DOES NOT DEPEND ON V. HOWEVER THE V IS THE ENERGY PER UNIT CHARGE , SO IF MORE ENERGY IS REQUIRED TO MOVE A CHARGE THAT MEANS THAT THE WIRE HAS MORE RESISTANCE. SO ACTUALLY RESISTANCE DOES DEPEND ON THE POTENTIAL DIFFERENCE. NOW IN THE CASE YOU HAVE STATED , YOU HAVE ACTUALLY PROVED WHAT I WANTED TO PROVE. YOU HAVE CONSIDERED V = 0 , i = 0 , SO YOU SAID THAT THE RESISTANCE COULD BE ANYTHING AND EVEN 10 OHMS AND IT DOES NOT DEPEND ON V. BUT THAT IS EXACTLY MY POINT. V/R = i , WHEN V AND R ARE BOTH 0 , I COULD BE ANYTHING AND EVEN 0. SEE YOU CANNOT ACTUALLY DENY THIS , BECAUSE I HAVE USED YOUR EXAMPLE TO PROVE MY STATEMENT AND MY DOUBT. THANK YOU

@@jsaifi7402 But what about your example where you yourself proved that 0/0 = 10 , u said there was no battery , so v = 0 , so i = 0 , so v/i = 0/0 , and you yourself said that the resistor could have any resistance , like you said that the resistance was 10ohms , so 0/0 = 10 , similiarly with respect to the chapter electricity 0/0 can be anything(the resistance could be anything)
