Question
A conducting bar of length L-80 cm is rotated on a conducting circular platform as shown in the
figure. 50 kQ-resistor and 40 µF capacitor are attached on the platform and an outward uniform
magnetic field of magnitude 12 mTis applied to the medium. If the bar rotates with a constant angular
speed of w-5 rad/s, what is the instantaneous charge on the capacitor after 0.5 s from the beginning
of the motion if it is uncharged initially?
