Coulomb's law states that the force between two point charges varies as

  • A.the inverse square of the distance between them
  • B.the inverse of the distance between them
  • C.the inverse cube of the distance
  • D.the square of the distance

Answer: A

The force is \( F = Q_1 Q_2/(4\pi\epsilon_0 R^2) \), directed along the line joining the charges and repulsive for like signs. The inverse square dependence is what makes Gauss's law take so simple a form in three dimensions.
