The correct description of how the Coulomb force affects charge interactions is: Like charges repel, and opposite charges attract.
In more detail:
- Like charges (both positive or both negative) experience a repulsive force, meaning they push away from each other.
- Opposite charges (one positive and one negative) experience an attractive force, meaning they pull towards each other.
This behavior is fundamental to electrostatics and underlies many physical phenomena involving electric charges.
