There are two identical, positively charged conducting spheres fixed in space. The spheres are 39.8 cm apart (center to center) and repel each other with an electrostatic force of F1 = 0.0615 N. Then, a thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2 = 0.100 N. Using this information, find the initial charge on each sphere, 91 and 92 if initially...
