1. The two very very large plates below are oppositely charged. Compare the electric

2. A beam of protons is shot with an initial velocity of 2 x 106 m/s at a metal plate. This
plate has an electric potential 10 kV higher than the proton beam source. The mass of
a proton is 1.7 x 10-27 kg, and the charge of a proton is 1.6 x 10-19 C. What is the
velocity of the protons just prior to striking the plate? (Hint: Tell me a physics story with
pictures and diagrams before you plug all sorts of numbers into equations. You may
use the back of this paper if you need to.)
