Question

Quizplus · Accepted Answer

According to Coulomb's law, the magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. Since the law applies equally to both charges involved, the force experienced by each charge due to the other is the same in magnitude but opposite in direction, regardless of their individual charge magnitudes.
