A uniform electric field (thatis, ~E is the same at every point) exists in a region between oppositely charged plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate, 2.0cm away, in atime 1.5 10^-8 seconds.
a) What is the speed of the electron as it strikes the second plate?
b) What is the magnitude of the electric eld ~E ? (You need kinematics for this one.)
