Four equal charges are located at the corners of a square of side d. If the magnitude of each charge is doubled, then what happens to the resultant force on each charge?

Question

Quizplus · Accepted Answer

The force between two charges is given by Coulomb's law, which states that the force is proportional to the product of the magnitudes of the charges. If each charge is doubled, the product of the charges becomes four times larger, thus quadrupling the force.
