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.
a) is a wrong answer, b,c,d are correct.
w=qB/mass The radius is determined by q,B and mass, and velocity.
