1. The problem statement, all variables and given/known data Part A - (Already solved) The electric potential at point A is 1800V. Part B - What is the potential energy of an electron at point A in the figure? Point A is .01m away from a charge of +2nC 2. Relevant equations V=Uq U = (Kq1q2)/r 3. The attempt at a solution I think the problem is, is that I am confused about the difference between electric potential and potential energy. This problem shouldn't be difficult. So I tried the second equation U = (9.00*10^9)(1.6*10^-19)(2*10^-9)/.01 U = 2.88*10^-18 But that isn't the answer...I don't know what equation I should use or what I am doing wrong.
