In the figure, a particle moves along a circle in a region of uniform magnetic field of magnitude $B=3.2\mathrm{mT}$. The particle is either a proton or an electron (you must decide which). It experiences a magnetic force of magnitude $2.8\times 10^{-15}\mathrm{N}$. What are (a) the particle's speed, (b) the radius of the circle, and (c) the period of the motion?
