Task id12989

An electron with kinetic energy W = 10,000 eV flies into a flat capacitor, between the plates of which a constant potential difference V = 40 V is maintained (Fig. 101), The distance between the plates is d = 1 cm, the length of the capacitor plates is l = 10 cm. At a distance L = There is a screen 20 cm from the capacitor. The initial speed of the electron is directed parallel to the plates. Find the displacement x of the electron on the screen. How will the answer change if instead of an electron we take a proton of the same energy?
