A pair of charged conducting plates produces a uniform field of 12,000 N/C, directed to the right, between the plates. The separation of the plates is 40 mm. An electron is projected from plate A, directly toward plate B, with an initial speed vo = 2.0 x 107m/s. What is the speed of the electron just as it strikes plate B?
