An electron (q = -1.602 x 10-19 C) is projected horizontally into the space between two oppositely charged metal plates. The electric field between the plates is 572.0 N/C, directed up.
(a) While in the field, what is the force on the electron?
(b) If the vertical deflection of the electron as it leaves the plates is 3.30 mm, how much has its kinetic energy increased due to the electric field?
