An electron, initially at rest on the negative plate of a parallel plate apparatus, is accelerated through the hole of the positive plate, after which it maintains a constant speed in a uniform magnetic field of 0.15 T. The speed as it leaves the plates and enters the magnetic field is 6.5 x 106 m/s.

(a) Determine the voltage across the parallel plates.

(b) Determine the initial magnetic force (magnitude and direction) experienced by the electron as it enters the magnetic field.

(c) Determine the radius of the electron's path while it is in the uniform magnetic field.

Answer rating: 100% (QA)

a To determine the voltage across the parallel plates we can use the workenergy principle The work done on the electron as it moves from the negative plate to the positive plate is equal to the change ... View the full answer
