A metal ring is held horizontally and bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet

A

equal to g

B

less than g

C

more than g

D

depends on the diameter of the ring and length of magnet

Text Solution

Verified by Experts

The correct Answer is:
