Answer: Coulomb's law says: F = [tex]k*\frac{q1*q2}{r^{2} }[/tex] where F is the force, q1 and q2 are the charge of both objects, k is a constant and r is the distance between the objects.
Here you can see that the relation between the electrical force and the separation between two charged objects is a inverse squared relationship.
so F is proportional to [tex]\frac{1}{r^{2} }[/tex], meaning that if r crease, then F must decrease (which has a lot of sense).
