According to Coulomb's law, the force between two charges decreases as the square of the distance between them increases, leading to a quarter of the original force when the distance is doubled.
Coulomb's law states that the force between two charges decreases as the square of the distance between them increases. When the distance is doubled, the force becomes one-fourth of its original value. Therefore, if the distance between two positive charges is doubled, the force of repulsion decreases to a quarter of the original force.
