A rod has a total charge Q uniformly distributed along its length L. If the rod rotates with angular velocity `omega` about its end, compute its magnetic moment.

A

`1/3qR^2omega`

B

`2/3qR^2omega`

C

`1/5qR^2omega`

D

`2/5qR^2omega`

Text Solution

Verified by Experts

The correct Answer is:
C
`M/L=q/(2m)`
`:. M=(q/(2m))L=(q/(2m))(Iomega)`
`=(q/(2m))(2/5mR^2omega)=1/5R^2omega`
