Question

Electric Potential Question:

Answer 1

A charged particle (q = 08.0 mC), which moves in a region where the only force acting on the particel 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 \[V _{b}-V _{a}\]?

Answer 2

potential difference is energy per unit charge

so it's the same as the work done on a unit charge passing between points with that potential difference
