Question

An electron moving around the nucleus with an angular momentum I has a magnetic moment

• A. $\frac{e}{m}l$
• B. $\frac{e}{2m}l$
• C. $\frac{2e}{m}l$
• D. $\frac{e}{2\pi m}l$
• E. $\frac{e}{4\pi m}l$

Answer 1

Answer: (B)

$\frac{\mu }{L}=\frac{1}{2}\frac{e}{m}$ $\mu =\frac{1}{2}\frac{eL}{m}=\frac{eL}{2m}$
