84 In Fig. 22-68, a uniform, upward
electric field E of magnitude 2.00 x
10° N/C has been set up between two
horizontal plates by charging the
lower plate positively and the upper
plate negatively. The plates have Figure 22-68 Problem 84.
length L = 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 e = 45.0° with the lower
plate and has a magnitude of 6.00 x 10° m/s. (a) Will the electron
strike one of the plates? (b) If so, which plate and how far horizon-
tally from the left edge will the electron strike?
