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 uF capacitor are attached on the platform and an outward uniform magnetic field of magnitude 12 mT is 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? L=80 ch www R=50 kn C=40 F w=5 rads B=12 mT
