The time period of a vibration magnetome...

The time period of a vibration magnetometer is `T_(0)`. Its magnet is replaced by another magnet whose moment of inertia is 3 times and magnetic moment is `1//3` of the initial magnet. The time period now will

A

`3T_(0)`

B

`T_(0)`

C

`T_(0)//sqrt3`

D

`T_(0)//3`

Text Solution

Verified by Experts

The correct Answer is:
A
`T= 2pi sqrt((3I)/((M)/(3).B))= 3T_(0)`
