Are we supposed to pick one?
The so-called cyclotron frequency of a charged particle in a magnetic field is proportional to B q/m. See
http://en.wikipedia.org/wiki/Cyclotron
One of the first four choices is correct.
The frequency of circular motion for a charged particle moving around in the presence of a uniform magnetic field does not depend on ...
The radius of the circle
The mass of the particle
The charge of the particle
The magnitude of the magnetic field
Actually, it depends on all of the above quantities
