A conducting disc of radius a and mass m is kept rotating with a constant angular speed in a horizontal plane about a vertical axis in a uniform vertical magnetic field B as shown in figure One metal contact B is made at the circumference of the disc and another contact B is made in such a way that its distance from centre is always a 2 If the switch S is closed at t 0 then the value of current in the inductor Value of n is B x x at t In2 is R en R L S 3Boa nR B a 2 xxxx
