Which of the following options is correct for Coulomb's law?

Explanation

The correct answer is Valid for only point charge. Key Points Coulomb's law:- It is a fundamental law of electrostatics that describes the interaction between electric charges. It states that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. While Coulomb's law is only valid for point charges, the principle can be extended to calculate the force between distributed charges by treating them as a collection of point charges. Coulomb's law is a fundamental principle that is used extensively in electrostatics, including in the design of electrical circuits and devices. Additional Information A point charge is a theoretical concept used to describe a charge that is concentrated at a single point in space. Distributed charges are charges that are spread out over a surface or volume.
