Решение задачи по физике раздел 72 пункт 43 электро

43. An electron moving at a speed of 4 ∙ 107 m / s flies into the space between the two plates of the capacitor parallel to them. The length of the plates of the capacitor is 6 cm, the distance between the plates is 0.5 cm. A voltage of 40 V is applied to the capacitor. How much does the electron speed at the output of the capacitor increase in modulus? compared to the initial?
