52. An electron flies into a flat capacitor with a speed υ0 (υ0 << с), parallel to the plates, the distance between which d. What is the potential difference between the plates of the capacitor if, upon departure from the capacitor, the electron velocity vector deviates from the initial direction by an angle α? Plate length l (l >> d).
