If the charge to mass ratio of an electron is ' $\mathrm{A}$ ' $\mathrm{C} / \mathrm{kg}$, then the gyromagnetic ratio of an orbital electron in $\mathrm{C} / \mathrm{kg}$ is
  1. $\frac{\mathrm{A}}{4}$
  2. $\mathrm{A}$
  3. $2 \mathrm{~A}$
  4. $\frac{\mathrm{A}}{2}$

Solution

$\text { Gyromagnetic ratio }=\frac{\text { Magnetic Moment }}{\text { Angular Momentum }}=\frac{\mathrm{e}}{2 \mathrm{~m}}=\frac{\mathrm{A}}{2}$ ~
