Bohr Model: Orbits, Speed & Angular Momentum

The magnetic moment of an electron (e) revolving in an orbit around nucleus with an orbital angular momentum is given by:

Show answer and solution

Answer: (b)

$\mu = IA = \frac{e}{2m}L$ in magnitude.
Electron charge is $-e$ , so $\vec{\mu}_L$ is opposite to $\vec{L}$ .
So the answer is (b) $\vec{\mu}_L = -\frac{e\vec{L}}{2m}$ .
