An electron is travelling horizontally with speed Vx = 40 km/s when it passes into a region of uniform, a downward electric field with magnitude E = 950 N/C. The field is generated by two horizontal plates with equal (and opposite) charges that are separated by a distance d = 2.5 mm. When the electron enters this region, it is midway between the two plates. What angle does the electron's velocity vector make with respect to the horizontal when it crashes into one of the plates? For the limits check, investigate what happens to as the plates become extremely close together (d 0). Note: the effects of gravity can be neglected in this problem.
