simple and common technique for accelerating electrons is shown in the figure below, where there is a uniform electric field between two plates © L 39% 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 in meters per second squared of the electron if the field strength is 3.20 x104 N/C. m/s2 (b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.
