44. An electron moving at a speed of 40,000 km / s flies into the space between two parallel plates of a flat capacitor. The length of the plates is 6 cm. The distance between the plates is 0.5 cm. A voltage of 40 V is applied to the capacitor. How much will the speed of the electron at its exit from the capacitor increase compared to the initial?
