The correct answer is Option (4) → Coulomb’s law
NCERT (2026-27):
Coulomb’s Law – “Coulomb’s law is a quantitative statement about the force between two point charges. … Coulomb measured the force between two point charges and found that it varied inversely as the square of the distance between the charges and was directly proportional to the product of the magnitude of the two charges and acted along the line joining the two charges.”
