In the circuit shown in figure, A is a sliding contact which can move over a smooth rod PQ. Resistance per unit length of the rod PQ is 1 ohm per meter .Initially slider is left to the point P and circuit is in the steady state. At t = 0 slider starts moving with constant velocity v =5m/s towards right. Current in the circuit at t = 2sec is |
