This is described by Coulomb's Law:

F = k * (q1 * q2) / r²

Where:

* F is the electrical force

* k is Coulomb's constant

* q1 and q2 are the magnitudes of the charges

* r is the distance between the charges

As you can see from the equation, the force (F) is inversely proportional to the square of the distance (r²). This means that:

* If the distance increases, the force decreases.

* If the distance decreases, the force increases.

Example: If you double the distance between two charges, the electrical force between them will become four times weaker.
