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

\vec\mu_L=\dfrac{e\vec L}{2m}

\vec\mu_L=-\dfrac{e\vec L}{2m}

\vec\mu_l=-\dfrac{e\vec L}m

\vec\mu_l=\dfrac{2e\vec L}m

Answer and worked solution

Official answer: B

Negative charge. $\vec\mu_L=-\dfrac e{2m}\vec L$ .
