##### Reference no: EM13240649

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 1.75 × 106 V and then enters a uniform magnetic field whose magnitude is 2.12 T. The ?-particle moves perpendicular to the magnetic field at all times. What is

(a) the speed of the ?-particle,

(b) the magnitude of the magnetic force on it, and

(c) the radius of its circular path?
