84 In Fig. 22-68, a uniform, upward electric field E of magnitude 2.00 x 103 N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length Z = 10.0 cm and separation d = 2.00 cm. An electron is then shot between the plates from the left edge of the lower plate. The initial velocity vo of the electron makes an angle 0 = 45.00 with the lower plate and has a magnitude of 6.00 x 105 m/s. (a) Will the electron strike one of the plates? (b) If so, which plate and how far horizontally from the left edge will the electron strike? E d VO L
