Problem

Which expression gives the angular frequency

\omega

of a particle of mass

m

and charge

q

moving at right angles to a uniform magnetic field of magnitude

B

? a)

\displaystyle \omega=\dfrac{qB}{2\pi m}

\displaystyle \omega=\dfrac{qB}{2m}

\displaystyle \omega=\dfrac{qB}{m}

\displaystyle \omega=2\pi\dfrac{qB}{m}
