1. The problem statement, all variables and given/known data A charged particle (q = -8.0 mC), which moves in a region where the only force acting on the particle is an electric force, is released from rest at point A. At point B the kinetic energy of the particle is equal to 4.8 J. What is the electric potential difference VB-VA? 2. Relevant equations EPE = Delta V (volts) = Delta U (potential energy) / q0 3. The attempt at a solution Using this equation, I came up with the solution of -.6 kV, however, the answer is positive. Why is this?
