49. An electron flies into a flat capacitor parallel to its plates at a speed of 1 ∙ 106 m / s. The length of the plate is 9 cm, the distance between the plates is 1.6 cm, the potential difference is 10 V. What speed does the electron have when it leaves the capacitor? What is the direction of this speed?
