An alpha particle can be produced in certain radioactive decays of nuclei and consists of two protons and two neutrons. the particle has a charge of q = +2e and a mass of 4.00 u, where u is the atomic mass unit, with

1μ= 1.661×10^−27kg

suppose an alpha particle travels in a circular path of radius 4.50 cm in a uniform magnetic field with b = 1.20 t. calculate
(a) its speed.
(b) its period of revolution.
(c) its kinetic energy.
(d) the potential difference through which it would have to be accelerated to achieve this energy.
