Solve the all parts of given question:

Question: Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.122 N when their center-to-center separation is 60.8 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 0.0319 N. Of the initial charges on the spheres, with a positive net charge

Part A: What was the negative charge on one of them?

Part B: What was the positive charge on the other? (Assume the negative charge has smaller magnitude.)

Please explain each step for above question.
