An electron initially at rest moves from one plate of a capacitor to another, through a potential di?erence of 2476 V.
a) Find the speed with which the electron strikes the positive plate. The electron's mass is 9.109 × 10?31 kg and the elemental charge is 1.602 × 10?19 C.
b) If a proton similarly moves from the positive plate to the negative plate, find the speed with which the proton strikes the negative plate.
