1. The problem statement, all variables and given/known data A 2.5C charge is moved from a point with a potential of 12V to another point of potential 75V. How much work was done on this charge? 2. Relevant equations ΔV = ΔEp/Q 3. The attempt at a solution I am unsure how to do this question but what I did do is I took the two potentials and I subtracted the two to get a difference in potential. Then I took that difference in potential and divided it by the charge of 2.5C to get the change in voltage. Now that I have the change in voltage what equation am I supposed to use to find the amount of work done?
