A conducting ring of radius L 2m is placed on X Y plane having its centre at the origin as shown in the figure A uniform magnetic field 5T k exists in the space A conducting rod PQ of mass M and length 2L is placed along the diameter of the rail as shown Rod is free to rotate about z axis on the smothering A resistance R is connected to the centre O and periphery of the ring At t 0 the rod PQ is given an angular velocity 1 k rad sec Find the ratio of the numerical values of the charge flown through the resistor to the heat generated through the resistor during the time interval the rod keeps on rotating P R www Z O
