# Question

An electron starts from one plate of a charged closely spaced (vertical) parallel plate arrangement with a velocity of 1.60 x 104 m/s to the right. Its speed on reaching the other plate, 2.10 cm away, is 4.15 x 104 m/s.

(a) What type of charge is on each plate?

(b) What is the direction of the electric field between the plates?

(c) If the plates are square with an edge length of 25.4 cm, determine the charge on each.
