Suppose that a wire leads into another, thinner wire of the same material that has only half the cross-sectional area. In the

steady state, the number of electrons per second flowing through the thick wire must be equal to the number of electrons

per second flowing through the thin wire. If the electric field E1 in the thick wire is 1 × 10−2 N/C, what is the electric field

E2 in the thinner wire?
