Question

The figure shows a long fixed wire AB carrying constant current I Another wire XY parallel to AB of mass per unit length is kept at a distance r from wire AB connected to a capacitor of capacitance C by flexible light wires through a switch The capacitor is initially charged to voltage E The switch is closed at t 0 and the circuit has a negligible The velocity of the wire XY just after closing the switch will be A Ho CE 4 r B Ho CE 2 r L C C D Ho CE 2 r Ho CE 48 Luo IC B 1 A Y X
