An particle has a charge of 2e and a mass of 664 1027 kg It

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 1.12 106 V and then enters a uniform magnetic field whose magnitude is 1.80 T. The ?-particle moves perpendicular to the magnetic field at all times.

(a) What is the speed of the ?-particle? m/s

(b) What is the magnitude of the magnetic force on it? N

(c) What is the radius of its circular path?

Solution

Note: I\'ve neglected all relativistic effects. If someone below me would like to, try including them. I don\'t really know how in this kind of problem.

The force acting on the particle:
F = q*v
