A plastic pellet has a mass of 7.5 X 10^-10 kg and carries a charge of 2.00 X 10^-9 C. The pellet is fired horizontally betweenm a pair of oppositely charged parallel plates. If the electric field strength between the plates is 9.20 X 10^4 N/C and the pellet enters with an initial speed of 150 m/s, determine the deflection angle.

This is the diagram

*I am almost positive that this problem can be solved by taking the arctan of the change in X over the change in y but i am not sure how to get there. Not in this sense anyway. I can solve these sort of problems when they are not part of electricity.
