What is the characteristic of the force between two point charges according to Coulomb’s law?

Principles of Electrostatics

Coulomb's Law: Describes the force between two point charges, establishing that the force is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Superposition Principle: States that the total force on a particular charge in an electric field is the vector sum of the individual forces exerted by other charges in the field.
Conservation of Charge: A fundamental principle in electromagnetism indicating that the net charge in an isolated system remains constant, meaning charge can neither be created nor destroyed.

Characteristics of Charge Distribution

Point Charge Distribution: Coulomb's law applies specifically to point charges, which are idealized charges that are concentrated at a single point in space.
Force Characteristics: According to Coulomb's law, the force between two point charges is attractive if the charges are of opposite signs and repulsive if they are of the same sign. The magnitude decreases as the distance between the charges increases.
