Figure QB2a shows the layout of a pair of parallel plates, one at a voltage of 0V, the other at +4000V. The plates are separated by a distance, = 25cm. An electron gun is placed immediately to the left of the plates and exactly halfway between them. The gun fires a single electron. Describe the path that the electron will follow as it travels between the plates. Explain why the electron will follow this particular trajectory.

)A uniform magnetic field is introduced into the experimental layout
shown in figure QB2a, with the field pointing directly out of the page.
The field has a magnetic flux density with a magnitude of 3.2x10^-3T
and affects the entire area between the parallel plates.
Determine the speed at which the electron must be travelling if the
effect of the magnetic field on the motion of the electron as it travels
between the plates is equal in magnitude, but opposite in direction, to
the effect of the parallel plates.
answer = 5x10^6m/s
