A horizontally-projected beam of protons travelling at 55 km/s travels between two parallel plates separated by 7.4 cm, and 12 cm long, between which there is an electric field of 7.2 mV/m upward. If the beam enters the region at exactly midway vertically between the plates, and exits the region 7.2 microns closer to the lower plate, where relative to the lower plate would a beam of electrons – injected into the region at the same location – exit? The proton mass is 1.67 x 10-27 kg and that of the electron is 9.11 x 10-31 kg.
A. 0.9 cm B. 5.1 cm C. 2.3 cm D. 4.6 cm
