58. An electron flying horizontally at a speed of 10 Mm / s flies into a flat capacitor parallel to its plates. The voltage between the plates of the capacitor is 300 V, the distance between the plates is 3 cm, the length of the plates of the capacitor is 5 cm. Find the magnitude of the electron velocity when it leaves the capacitor.
