An ?-particle has a charge of +2e and a mass of 6.64 ? 10-27 kg. It is accelerated from rest through a potential difference that has a value of 1.06 X 106 V and then enters a uniform magnetic field whose magnitude is 3.10 T. The ? -particle moves perpendicular to the magnetic field at all times.
(a) What is the speed of the ?-particle?
(b) What is the magnitude of the magnetic force on it?
(c) What is the radius of its circular path?
