If the angular momentum of an electron is `vec(J)` then the magnitude of the magnetic moment will be

A

`(eJ)/m`

B

`(eJ)/(2m)`

C

`eJ 2m`

D

`(2m)/(eJ)`

Text Solution

Verified by Experts

The correct Answer is:
B

As we know for circulating electron magnetic moment
`M=1/2evr`
and angular momentum
`J=mvr`
From equation (i) and (ii) `M=(eJ)/(2m)`
