In the figure, a particle moves along a circle in a region of uniform magnetic field of magnitude B = 4.2 mT. The particle is either a proton or an electron (you must decide which). It experiences a magnetic force of magnitude 3.0 x 1015N. What are (a) the particle's speed, (b) the radius of the circle, and (c) the period of the motion? The tolerance is ± 1 in the 2nd significant digit. OB
