Q125 / 155 · WBJEE 2025 · Physics

A particle of charge ' $q$ ' and mass ' $m$ ' moves in a circular orbit of radius ' $r$ ' with angular speed ' $\omega$ '. The ratio of the magnitude of its magnetic moment to that of its angular momentum depends on

A
$\quad \omega$ and q
B
$\omega, q$ and $m$
Correct answer
C
q and m
D
$\quad \omega$ and $m$

Solution

Gyromagnetic ratio, $\frac{M}{L}=\frac{q}{2 m}$

Hence, the correct answer is option: 'C'.
