The velocity of a proton emerging from a Van de Graaff accelerator is 25.0% of the speed of light. What was the equivalent voltage through which it was accelerated? The mass of a proton is 1.67 \times 10^{-27} ~\text{kg}1.67×10 −27 kg. (Recall that the kinetic energy gained is equal to the electric potential energy lost as a charged particle moves through ad potential difference, ie. q \Delta V = \Delta KEqΔV=ΔKE.)
