The figure shows wire section 1 of diameter D₁ = 5.50R and wire section 2 of diameter D₂ = 4.00R, 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 = 1.90 m shown in section 2 is 9.00 μV. The number of charge carriers per unit volume is 8.20 x 1028 m3. What is the drift speed of the conduction electrons in section 1? (1) TLA (2) 4
