Why is Coulomb's law of electrostatics considered as an inverse square law?

Coulomb's law of electrostatics is considered an inverse square law because it describes the relationship between the force of attraction or repulsion between two charged objects as inversely proportional to the square of the distance between their centers. Mathematically, the law is expressed as
an inverse square relationship signifies that as the distance between two charges increases, the force between them decreases rapidly, following the square of the distance. This behavior is characteristic of phenomena where a quantity or intensity spreads uniformly over the surface of a sphere centered on the source, resulting in a proportional decrease in strength with the square of the distance from the source. Coulomb's law is analogous to Newton's law of universal gravitation and other physical laws exhibiting inverse square relationships.
