In the accompanying figure, the rails, connecting end piece, and rod all have a resistance per unit length of 2.0 Vcm. The rod moves to the left at v = 3.0 m/s. If B = 0.75T everywhere in the region, what is the current in the circuit (a) when a = 8.0cm? (b) when a = 5.0 cm? Specify also the sense of the current flow. 4.0 cm
