An alpha particle (q = +2e, m = 4.00 u) travels in a circular path of radius 5.10 cm in a uniform magnetic field with B = 1.17 T. Calculate (a) its speed, (b) its period of revolution, (c) its kinetic energy, and (d) the potential difference through which it would have to be accelerated to achieve this energy. %3D
