When two identical conducting spheres are held in place and their center-to-center spacing is 42.5 cm, they attract each other with an electrostatic force of 0.019 N. A tiny conductive wire connects the spheres after that. The spheres repel each other with an electrostatic force of 0.0360 N when the wire is removed. With a positive net charge, what was (a) the negative charge on one and (b) the positive charge on the other of the original charges on the spheres?
