An alpha particle travels at a velocity of magnitude 420 m/s through a uniform magnetic field of magnitude 0.061 T. (An alpha particle has a charge of charge of +3.2 x 10-19 C and a mass 6.6 x 10-27 kg) The angle between the particle's direction of motion and the magnetic field is 49°. What is the magnitude of
(a) the force acting on the particle due to the field, and
(b) the acceleration of the particle due to this force?
