Consider two wires A and B, in which the number of electrons flowing per unit of time is the same. The wires are identical in terms of material, but the diameter of wire A is 0.8 cm, and of wire B is 1.6 cm. If in wire A electron drift speed is 3.2 × 10-4 m/s, find the electron drift speed in wire B.
