Magnetic moment of revolving electron of charge (e) and mass (m) in terms of angular momentum (L) of electron is
  1. $\frac{\mathrm{eL}}{8 \mathrm{~m}}$
  2. $\frac{\mathrm{eL}}{4 \mathrm{~m}}$
  3. $\frac{\mathrm{eL}}{2 \mathrm{~m}}$
  4. $\frac{\mathrm{eL}}{\mathrm{m}}$

Solution

The gyromagnetic ratio of the electron $\frac{\mathrm{M}}{\mathrm{L}}=\frac{\mathrm{e}}{2 \mathrm{~m}}$ or $M=\frac{e L}{2 m}$
