Q. An electron moving around the nucleus with an angular momentum I has a magnetic moment
KEAM
KEAM 2011
A
$ \frac{e}{m}l $
B
$ \frac{e}{2m}l $
C
$ \frac{2e}{m}l $
D
$ \frac{e}{2\pi m}l $
E
$ \frac{e}{4\pi m}l $
Solution:
$ \frac{\mu }{L}=\frac{1}{2}\frac{e}{m} $ $ \mu =\frac{1}{2}\frac{eL}{m}=\frac{eL}{2m} $
