The cyclotron frequency of a particle of mass $m$ and charge $q$ in field $B$ is:
A$2\pi qB/m$, missing the divide in the formula here
B$qBm$, the product of all three quantities together
C$mB/q$, with mass and field divided by charge instead
D$qB/(2\pi m)$, the standard cyclotron frequency expression
Answer & Solution
Correct answer: D. $qB/(2\pi m)$, the standard cyclotron frequency expression
$f = qB/(2\pi m)$ is the cyclotron frequency.
