A uniform electric field exists in a region between twooppositely charged plates. An electron is released from restat the surface of the negatively charged plate and strikes thesurface of the oppostie plate, 2.0 cm away, in a time1.5X10^-8s
a) What is the speed of the electron as it strikes the secondplate?
b) What is the magnitude of the electric field E?
