At t=0 the switch s of the adjacent network is closed. The connector has mass m, length l and resitanceR; it is free to move on the rails. The capacitance of the capacitor is C. It is initially uncharged and a uniform magnetic field exists into the plane of the paper. What is the charge on the capacitor after a long time??...........answer is EmC/( C2B2l2 + m)..........please post the solution specially the portion wher velocity of the connector is substituted.
