A beam of chlorine ions Cl35 and Cl37, each carrying one elementary positive charge, is accelerated so that the velocities of the ions by the time the beam enters the space between the plates of a flat capacitor are the same and equal to v0 = 107 cm/sec. The beam flies into the middle of the capacitor parallel to its plates. The length of the plates is l = 5 cm, the distance between them is d = 5 mm. What voltage V must be applied between the capacitor plates so that the points of impact of the Cl35 and Cl37 ions are 0.6 mm apart on the receiving screen? The receiving screen is located at a distance L = 10 cm from the rear edge of the capacitor plates.
