Question
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?
