In the fugure, a particle moves along a circle in a region of uniform magnetic field of magnitude $B=3.5\mathrm{mT}$. The particle is either a proton or a in efectron (you must decide which). It experiences a magnetic force of magnitude $3.3\times 10^{-15}\mathrm{N}$. What are (a) the particides speed, (b) the radlus of the circle, and (c) the period of the motion? (a) Number Units (b) Number Units (c) Number Units
