For those of you looking for bare bones answer to this question. Just take the negative gradient of your electrical potential equation, that is take the derivative of the equation with respect to x, then y of the original, and then z of the original and assign x hat, y hat, and z hat respectively.

Thanks. Slightly confused by why the absolute value of the potential due to the charged sheet is proportional to z. Wouldn't it reduce with greater displacement from the sheet? i.e. wouldn't it be proportional to 1/z, in the same way as potential due to a point charge is proportional to 1/r?

Is this Physics or Mathematics, or is it symply an event of voicing formulas that one can simply look in the books? Does anyone wonder how these equations came into being? ..."epsilon nought" "arrhh to the minus two" ""some constant sigma", seriously, is this an explanation, or just dictation? Good Sir, you are not a professor, but a student at an exam. I doubt you yourself understand what you teaching. Reading the zeroes and the ones as values off of a compact disc doesn't generate music in my ears. Kudos to those for whom it does.

@@yoprofmatt Dear Matt Anderson, thanks a lot. I shall have a look. I will share my views on how to get the electric field from electric potential shortly. In short, I would think the way would be to start with Force, then define the electric field and show that the curl of the electric field is zero for static charge configurations. Then one can introduce the concept of the potential energy of a system of charges. The work done by "me" on the charges would connect force and the stored potential energy. One would then introduce the concept of Potential as the work done per unit charge. Now that makes the relation between Potential and the work done per unit charge which essentially is V = -Integral (F.ds/Q), where V is the potential and F is the force and ds is the infinitesimal displacement, the minus appears due to the fact that the force and the displacement are in the opposite direction. But F/Q = E, therefore you end up getting V = -Integral (E.ds), note that this path integral on the line is possible because of the fact that in electrostatics the curl of E goes to Zero, as the force is conservative. Best wishes.
