1. The problem statement, all variables and given/known data (a) Find the electric potential at a distance of 1.00 cm from a proton. (b) what is the potential difference between two points that are 1.00 cm and 2.00 cm from a proton? 2. Relevant equations I know delta V has to be set equal to something but im not sure what 3. The attempt at a solution Im not certain of the method to go about this problem. Please Help.
