Question
A simple and common technique for accelerating electrons is shown, where there is a uniform electric field between two plates. Electrons are released,
usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. (a) Calculate the acceleration of the electron if the field strength is 2.50×104 N/C .
(b) Explain why the electron will not be pulled back to the positive plate
once it moves through the hole.
