What is the electric field strength between the plates

Reference no: EM13707711

Solve the all parts of following problem:

Problem: The electron gun in an old TV picture tube accelerates electrons between two parallel plates 1.3cm apart with a 20kV 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?

I need help to solve the above question and express your answer to two significant figures and include the appropriate units.
