The perio of oscillation of a magnet in ...

The perio of oscillation of a magnet in vibration magnetometer is 2 sec. The period of oscillation of a magnet whosr magnetic moment is four times that of the first magnet is

A

`1 sec`

B

`4 sec`

C

`8 sec`

D

`0.5 sec`

Text Solution

Verified by Experts

The correct Answer is:
A
`T_(1)/T_(2)=sqrt(M_(2)/M_(1))=sqrt((4M)/M)=2 implies 2/T_(2)=2 implies T_(2)=1 sec`
