A conducting bar of mass m 1kg and length I 1m is in contact with a thin conducting circular ring as shown in the figure. The bar rotates about the pivot point o which is also the center of the ring. The ring and the bar are connected by a resistor R 10. A uniform magnetic field B= 1T is applied perpendicular to the rotating plane of the bar and the ring. The bar is released to rotate at t = 0 after reaching initial angular speed w, 100rad/s. Find the angular speed w of the rod att = 3s. (Assume that there is a good electrical contact between bar and the ring and ignore friction forces).

A conducting bar of mass m 1kg and length /= 1m is in contact with a thin
conducting circular ring as shown in the figure. The bar rotates about the pivot
point o which is also the center of the ring. The ring and the bar are connected
by a resistor R 10. A uniform magne tic field B 17 is applied perpendicular
to the rotating plane of the bar and the ring. The bar is released to rotate at t =
0 after reaching initial angular speed w, = 100rad/s. Find the angular speed w
of the rod att = 3s. (Assume that there is a good electrical contact between bar
and the ring and ignore friction forces).
