The formula for the potential energy between two charges in a system is expressed as:

1. U = (1/4πε₀)(q₁q₂/r)
2. Energy between two charges in a system
3. q₁q₂ divided by r
4. Not applicable

Correct answer: U = (1/4πε₀)(q₁q₂/r)

Solution

The formula U = (1/4πε₀)(q₁q₂/r) correctly represents the potential energy of a two-charge system as derived from Coulomb's law.
