Concept, principle, and explanation

According to Coulomb's Law, the direction of the force between two point charges lies along the line connecting them. Like charges repel each other, so the force direction is away from each other. Unlike charges attract each other, so the force direction is toward each other. Mathematically, it is determined by the sign of q₁ q₂ and the direction of the unit vector r.
