The electron gun in an old TV picture tube accelerates electrons between two parallel plates 1.3 cm apart with a 26 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. Part A What is the electric field strength between the plates? Express your answer to two significant figures and include the appropriate units. E = Submit Part B Vexit = μA Submit Value Request Answer With what speed does an electron exit the electron gun if its entry speed is close to zero? Note: The exit speed is so fast that we really need to use the theory of relativity to compute an accurate value. Your answer to part B is in the right range but a little too big.
