Final answer:
When two charged particles are released and move apart, the force between them decreases. The electrostatic force between charged particles follows an inverse-square law, which means that as the distance between the particles increases, the force between them decreases.
Step-by-step explanation:
The statement in the question, 'Two charged particles held close together to each other are released. As they move, the force on each particle increases,' is incorrect. When two charged particles are released and move apart, the force between them actually decreases. This is because the electrostatic force between charged particles follows an inverse-square law, which means that as the distance between the particles increases, the force between them decreases. For example, if the distance between the particles doubles, the force between them decreases by a factor of four.
