Interpretation:
The electrostatic potential energies between the given charges in the given statement should be calculated by using the concept of electrostatic energy.
Concept Introduction:
Energy is the ability to do work or transfer heat where work is the movement of a body using some force. The SI unit of energy is joule (
Electrostatic energy is potential energy which results from the interaction of charged particles. Oppositely charged particles attract each other and particles of like charges repel each other. The magnitude of the resulting electrostatic potential energy is proportional to the product of the two charges (
If the charges
