If only electric forces are important Conservation of Mechanical Energy tells us Kinit + Uinit = Kfinal + Ufinal. In practice the electric force is frequently much larger than the gravitational force, and we can eliminate frictional or drag forces by using a vacuum system. The the only potential energy is the electrostatic potential energy, U = q V. An electron has a speed of 5.0 x 105 m/s at point A. The voltage at point A is 3300 V and at point B is 4500 V.

(a) What is the speed of the electron at point B? Assume forces other than the electric force are negligible.

(b) Repeat the question for a proton instead of an electron. Notice the big difference between accelerating an electron and a proton.
