Homework Statement
A particle of charge q = e moves in a circle of radius = 0.44 m with speed v = 2.350×107 m/s. Treating the circular path as a current loop with constant current equal to its average current, find the maximum torque exerted on the loop by a uniform magnetic field of magnitude B = 1.00 T.
Homework Equations
R=mv/qB
The Attempt at a Solution
I'm stuck and I don't really know where to go. I did find the mass by the following equation:
m = rqB / v
m = 0.44 * 1.602E-19 * 1 / 2.35E7
m = 2.999E-27 kg
I could also find KE but I'm not sure what to do with either of these two. How does torque relate to magnetism?
