Question

Consider the arrangement shown in the figure in which the north pole of a magnet is moved away from a thick conducting loop containing a capacitor. Then excess positive charge will arrive on

• A. Plate $a$
• B. Plate b
• C. On both plates a and b
• D. On neither a nor b plates

Answer 1

The correct option is B Plate b

Here the north pole moving away from the magnet , so the induced current in the loop viewed from left side will flow in such a way that it will behave like a north pole so south pole developed in the coil when the right side of the loop . the flow of induced current is anti-clockwise so the plate B acquires positive charge .

hence B option is the correct answer
