Magnetism Question 248

Question: If the angular momentum of an electron is $ \vec{J} $ then the magnitude of the magnetic moment will be

Options:

A) $ \frac{eJ}{m} $

B) $ \frac{eJ}{2m} $

C) $ eJ,2m $

D) $ \frac{2m}{eJ} $

Show Answer

Answer:

Correct Answer: B

Solution:

[b] We know that, $ \frac{M}{J}=\frac{q}{2m} $
$ \

Therefore ,,,M=J\times \frac{e}{2m} $
