Question

The gyromagnetic ratio of an electron of charge $e$ and mass $m$ is equal to

• A. $\frac{e^2}{2m}$
• B. $\frac{e^2}{2m^2}$
• C. $\frac{e}{4m}$
• D. $\frac{e}{2m}$

Answer 1

Answer: (D)

The ratio of the angular momentum of an atomic system to its magnetic moment is known as its gyromagnetic ratio.
For an electron it is $\frac{e}{2m}$ .
