In the figure below, a particle moves along a circle in a region of uniform magnetic field of magnitude B = 3.50 mT. The particle is either a proton or an electron (you must decide which). It experiences a magnetic force of magnitude 3.37 10-15 N.
(a) What is the particle's speed?
m/s
(b) What is the radius of the circle?
m
(c) What is the period of the motion?
s
