Part C
The string is cut. What is the speed of each sphere when they are far apart?
Hint: There are two conserved quantities. Make use of both.

apart with a
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 using two significant figures.
