alleryThe cyclotron frequency of a particle in a uniform magnetic field B is
Af = m v / (qB)
Bf = qB / (2π m)
Cf = 2π m / (qB)
Df = qB · v
Answer & Solution
Correct answer: B. f = qB / (2π m)
Period T = 2π m/(qB), so frequency f = 1/T = qB/(2π m).
Note it is INDEPENDENT of the radius and the particle's speed (non-relativistic).
