How do you calculate the total electric potential energy for a system with multiple charges?

Calculate the potential energy for every unique pair of charges and then sum them up.

What is the first step in solving an electric potential energy problem?

Draw a diagram to visualize the problem and identify all charges and distances.

What is Electric Potential Energy?

Work done by an external force to bring charges from infinitely far apart to their current positions.

Define $U_E$ in the context of Electric Potential Energy.

Electric potential energy, measured in Joules (J).
