A short magnet is allowed to fall from rest along the axis of a horizontal conducting ring. The distance fallen by the magnet in one second may be

A

`5m`

B

`6m`

C

`4m`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
In case of free fall,
`d=1/2g t^2`
`=1/2(10)(1)^2=5m`
Here due to repulsion from inducd effects
`a lt g`
`:. dlt5m`
