The electric force between charged objects is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them. As the distance between charged objects increases, the electric force between them decreases. This is known as Coulomb's law, and it can be expressed mathematically as:
F = k * (q1 * q2) / d^2
Where F is the electric force between two charged objects, q1 and q2 are the magnitudes of the charges of the two objects, d is the distance between them, and k is the Coulomb constant.
As the distance between charged objects doubles, the electric force between them reduces to one-fourth of the original value. If the distance between them is tripled, the electric force reduces to one-ninth of the original value, and so on.
How does the distance between charged objects affect the electric force between them?
