Two square, oppositely charged conducting plates measure 20 cm on each side. The plates are close together and parallel to each other. They each have a total charge of +4.0nC and – 4.0nC, respectively.
(a) What is the electric field between the plates?
(b) What force is exerted on an electron located between the plates?
(c) What would be the electron’s acceleration if it were released from rest?
