Figure shows a conducting ring A conducting rod of length is hinged at the centre of the ring and its other end touches the ring such that the rod can rotate in the plane of the ring The hinge and the ring are connected by a resistance R There exists a uniform magnetic field given by B Bok in the region x 0 and B Bok if x 0 The rod rotates with constant angular velocity w anti clockwise and the direction of current in the resistance R is shown Taking this direction as positive and the instant shown in figure as t 0 draw a graph showing the variation of current with time B B K 100 4 y axis w C PI R PL www B B K x axis
