Figure shows the north pole of a magnet moving away from a thick conducting loop containing a capacitor. The excess positive charge will arrive on
Options
- Aplate 'a'
- Bplate 'b'
- Cboth plates 'a' and 'b'
- Dneither plate ' a ' nor plate ' b '
Correct answer
B. plate 'b'
Step-by-step solution
Magnetic flux analysis: The north pole moving away decreases rightward magnetic flux through the loop. Lenz's Law application: The induced current must generate a magnetic field opposing this decrease, pointing rightward through the loop. Current direction: A rightward magnetic field requires a clockwise current when viewed from the right. Capacitor charge accumulation: Clockwise current flows toward terminal b through the right side and from terminal a through the left side, implying current flows from a to b thro
