The frequency of circular motion for a charged particle moving around in the presence of a uniform magnetic field does not depend on ...

a)The radius of the circle
b)The mass of the particle
c)The charge of the particle
d)The magnitude of the magnetic field
e)Actually, it depends on all of the above quantities

I believe the answer is d because the magnetic field alone cannot alter the KE of a particle because it is perpendicular to the particle velocity

Is this correct?
