An electron flies into a flat air capacitor parallel to its plates with a speed = 6·10^5 m/s. The distance between the plates = 1 cm, potential difference = 339 V. The length of its plates is L = 5 cm. Determine the surface charge density on the capacitor plates (in μC / m ^ 2) and the linear deviation of the electron caused by the capacitor field (in mm).
