Question

Quizplus · Accepted Answer

If the force on each particle is increasing as they move, it means that they are moving towards each other. This would only happen if their charges have opposite signs. If their charges had the same sign, the force between them would decrease as they moved apart, not increase. Mass and size are not relevant factors in this scenario.
