A copper ring having a cut such as not to from a complete loop is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet is

A

is equal to g

B

is more than g

C

is less than g

D

depends upon the width of the gap

Text Solution

Verified by Experts

The correct Answer is:
A

As the ring is not a closed loop, induced e.m.f. is not produced and hence its motion is not affected.
