1. The problem statement, all variables and given/known data The potential at a point is -4.5E3 V. How much work, in J, is done to bring a 0.94 C charge from infinity to the point? 2. Relevant equations 1V = 1 J/C 3. The attempt at a solution Well I know that 1 V = 1 J/C so I did -4500V*0.94C = -4230J but I wasn't sure if this was right.
