Решение задачи по физике раздел 9 пункт 80 электро

80. Electronic flew into the plate capacitor, having the speed υ = 10 mm / s, directed parallel to the plates. At the moment of departure from the condenser direction of the electron velocity makes an angle of 35 ° to the original direction of the velocity. Determine the potential difference U between the plates (field considered uniform), if the length l plates is 10 cm and the distance d between them is equal to 2 cm.
