In the figure ab and cd are two long conduction wires kept parallel to each other at a separation in a uniform time varying magnetic filed The ends a and care connected together by a resistor of resistance R The magnetic induction B perpendicular to the plane of the wires varies with time according to the relation B Bot where B is a positive constant with proper unit and t is the time x Px x in second A conducting wire PQ placed on the wire ab and cd and dragged on the wires with constant speed valong the length of the wires by applying a constant force F Find the value of F in terms of the other given parameters At time t 0 PQ is very close to ac Ignore any resistance electric as well as mechanical other than R B 1 vt 4B 1 vt A B 2B 1 vt R C X a X XP C X X X X D X X D X 8B1 vt X X X X Q X X X X X d X
