1. The problem statement, all variables and given/known data . The problem statement, all variables and given/known data If the electric field does negative work on a negative charge as the charge undergoes a displacement from position a to b within an electric field then the electrical potential energy is? ANSWER: positive 2. Relevant equations none 3. The attempt at a solution So I know that W = -deltaU, and thus, if we have a negative coefficient for W, we would get a positive coefficient for deltaU, resulting in positive electrical potential energy. How could I think this problem through if I completely forgot the equation and just thought conceptually? Thanks in advance!
