The figure shows wire section 1 of diameter D1 = 4.00R and wire section 2 of diameter D2 = 2.00R, connected by a tapered section. The wire is copper and carries a current. Assume that the current is uniformly distributed across any cross-sectional area through the wire's width. The electric potential change V along the length L = 2.00 m shown in section 2 is 10.0 µV. The number of charge carriers per unit volume is 8.49 × 10^28 m^-3. What is the drift speed of the conduction electrons in section 1?
