An electron of charge $e$ and mass $m$ is moving in a circular of radius $r$ with a uniform angular speed $ω .$ Then which of the following statements are correct?

Options:(select one or more)

Answer:

B, D

Solution:

Magnetic moment, $m = I A$ $= \frac{e v}{2 π f} \times π r^{2} = \frac{e v r}{2}$ Angular momentum $= 2 m \frac{d A}{d t}$
