Coulomb's law states that the force between two point charges in vacuum is
AInversely proportional to the cube of the distance between them
BDirectly proportional to the distance between them
CInversely proportional to the square of the distance between them
DIndependent of the distance between them
Answer & Solution
Correct answer: C. Inversely proportional to the square of the distance between them
F = (1/4πε₀)·|q₁q₂|/r². The force is inversely proportional to the square of the separation — an inverse-square law.
