Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 1.0939 N when their center-to-center separation is 50 cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.1367 N. What were the initial charges on the spheres
