There are two objects, one with a +2 charge and one with a -2 charge. If we increase the distance between the two objects, what happens to the strength of the electric force?

As we increase the distance between the two objects, the strength of the electric force between them decreases. This is because the electric force is inversely proportional to the square of the distance between the objects, according to Coulomb's law. Therefore, as the distance between the objects increases, the electric force decreases proportionally.
decreases in proportion to the SQUARE of the distance.
twice as far is 1/4 the force
twice as far is 1/4 the force
Yes, that is correct. The strength of the electric force decreases in proportion to the square of the distance between the two objects. So, if the distance is doubled, the strength of the electric force becomes 1/4th of its original value.
