Q. The electron gun in a TV picture tube accelerates electrons between two parallel plates 1.5 cm apart with a 27 kV potential difference between them. The electrons enter through a small hole in the negative plate, accelerate, then exit through a small hole in the positive plate. Assume that the holes are small enough not to affect the electric field or potential.
What is the electric field strength between the plates?
