Which factor affects the electrostatic force between two charged objects?

The electrostatic force between two charged objects is principally governed by the distance separating them. According to Coulomb's Law, the electrostatic force is inversely proportional to the square of the distance between the charges. This means that as the distance increases, the force decreases significantly; conversely, as the distance decreases, the electrostatic force increases.

This relationship is fundamental to understanding how charged objects interact with one another. For example, if two charges are moved closer together, the force acting between them grows stronger, while pushing them further apart reduces the force considerably. This essential concept highlights the importance of the distance in determining the strength of the electrostatic force. Other factors, like temperature, color, and material of the objects, do not play a direct role in the fundamental relationship defined by Coulomb’s Law.
