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 5.50 x 104 N/C. m/s² (b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole. There is no field outside the plates.
