Angular Momentum of a Particle Experiencing a Magnetic Force

APPHEM-UGVOLV

A particle of charge $\mathit{q}$ and mass $\mathit{m}$ moves in a circular path of radius $\mathit{r}$ in a uniform magnetic field $\mathit{B}$.

The angular momentum of the particle can be described by the expression:

A

$\mathit{eBr}$

B

$\mathit{2eBr}$

C

$\mathit{eBr^2}$

D

$\mathit{eBr m_p}$

E

$\mathit{2eBr m_p}$
