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} $
