Question

A copper ring having a cut such that u does not form a complete loop is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. Then acceleration of the falling magnet is (A) g (B) less than g (C) more than g (D) zero

As the loop is incomplete so there will be no induced current in the loop. Hence, bar magnet will fall with acceleration due to gravity (g).

Q. A copper ring having a cut such that u does not form a complete loop is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. Then acceleration of the falling magnet is

g

less than g

more than g

zero

As the loop is incomplete so there will be no induced current in the loop. Hence, bar magnet will fall with acceleration due to gravity $(g)$ .
