The ratio of magnetic dipole moment to angular momentum of electron is

A

`(e)/(m)`

B

`(m)/(e)`

C

`(2m)/(e)`

D

`(e)/(2m)`

Text Solution

Verified by Experts

The correct Answer is:
D
Magnetic dipole moment=M=IA
`=(ev)/(2pir)pir^(2)=(evr)/(2)`
Angular momentum=Lltbrgemrv
Thus ,`(M)/(L)=(evr//2)/(mrv)=(e)/(2m)`
