Two charges separated by one meter exert a 1-N force on each other. If the charges are pushed to 0.25-m separation, the force on each charge will be

Question

Quizplus · Accepted Answer

According to Coulomb's law, the force between two charges is inversely proportional to the square of the distance between them. Reducing the distance to 0.25 meters (one-fourth of the original distance) increases the force by a factor of (1/0.25)^2 = 16.
