I've got a pretty quick question about magnetism.

A magnetic field, of 0.6 T, going into the paper, causes a charged particle to move in a horizontal circle. The particle has mass 1.67 x 10^-27 kg and charge 1.6 x 10^-19 C.

A. How long does it take for the particle to go once around the circle?

B. How many times per second does the particle go around the circle?

Relevant Equations: qvB = (mv^2)/R F = qvBsin(θ) Time = Distance/Velocity

I feel like there is a piece of information missing from this problem, I can't seem to solve it with any of the above equations. We don't know the velocity or radius of the circle so that rules the first equation out. We also don't know the magnitude of the magnetic force so that rules the second equation out.

Help is much appreciated.
