Coulomb’s law is applicable for _________.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Between two point charges.
Coulomb’s law is applicable between two point charges. It states that the electrostatic force between two stationary point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. The law assumes that the charges are point-like and not spread over a volume or surface. For distributed charges, Coulomb’s law must be applied using integration over the charge distribution, so it is not directly applicable in that form.
