An unknown element has a nucleus with a charge of 17e and a radius of about 4.9×10−15×10−15m. How much voltage must be used to accelerate a proton (radius 1.20×10-15 m) so that is has sufficient energy to just penetrate the unknown element? Assume that the potential is that for point charges. (Please answer in SI unit and multiply your answer by 10−610−6) please hurry, thanks.
