distribute uniformly on the spheres outer surface

Two identical conducting spheres carry charges of +5.0uC and +1.0uC. A distance L initially separates the centers of the spheres. The two spheres are brought together so that they are in contact. The spheres are then returned to their original separation L. What is the ration of the magnitude of the force on either charge after the spheres are touched to that before they were touched?
