42. An electron moving at a speed of 50 ∙ 106 m / s flies into the space between the plates of a flat capacitor. The distance between the plates is 0.3 cm, the length is 1 cm. A voltage of 60 V is applied to the capacitor. How much will the electron speed increase at the output of the capacitor compared to the initial speed
