Determine the electric field strength between the plates

Reference no: EM13280895

The electron gun in an old TV picture tube accelerates electrons between two parallel plates 1.2cm apart with a 28kV 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.

Part A What is the electric field strength between the plates?

Part B With what speed does an electron exit the electron gun if its entry speed is close to zero?
