Final answer:
The electrostatic force between charged objects increases as they get closer, inversely proportional to the square of the distance between them as per Coulomb's law.
Step-by-step explanation:
As charged objects get closer together, the size of the force between them changes significantly according to Coulomb's law. This scientific rule tells us that the electrostatic force is directly proportional to the product of the electric charges on the two objects, and inversely proportional to the square of the distance between them. This means that if the distance between two charged objects is halved, the force of attraction or repulsion between them becomes four times as strong. Conversely, if the distance is doubled, the force decreases to a quarter of its original strength.
The electrostatic force becomes significantly stronger as the distance between charged particles decreases. This is true for stationary charges and becomes more complex when charges are in motion. In a vacuum, oppositely charged particles will attract each other with increasing force as they move closer. If the charges are of the same sign, they will repel each other, also with increasing force as the distance between them diminishes.
