A pair of charged conducting plates produces a uniform field of Eo= 10,859 N/C directed to the right, between the plates. The separation of the plates is L= 37mm. An electron (e=1.6 x 10^-19 C; m9.1 x 10^-31 kg) is projected from plate A, directly toward plate B, with an initial velocity of Vo = 2.1 x 10^7 m/s. What is the velocity of the electron (expressed in general form as a whole number) as it strikes plate B?
