Quizplus · Accepted Answer

According to Coulomb's law, the force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. Doubling the charges increases the force by a factor of 4, but doubling the distance decreases the force by a factor of 4, resulting in no net change.
