If you double the distance between two objects, the electric force between them decreases by a factor of four.

Here's why:

* Coulomb's Law: The electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

* Mathematical Representation: F = k * (q1 * q2) / r²

* F = electric force

* k = Coulomb's constant

* q1 and q2 = charges of the objects

* r = distance between the objects

Doubling the distance:

* If you double the distance (r), you're essentially squaring the denominator in Coulomb's Law: (2r)² = 4r².

* Since the force is inversely proportional to the square of the distance, the force is reduced by a factor of 4.
