Solving a problem in physics section 72 point 51 electr

51. An electron flies into a flat capacitor, with horizontally located plates, having a speed of 104 m / s, parallel to the plates. At the time of departure from the capacitor, the electron velocity direction was an angle of 30 ° with the original direction. Determine the potential difference of the plates, if the length of the plates is 10 cm, the distance between them is 2 cm.
