Physics

Two identical conducting spheres, fixed in place, attract eachother with an electrostatic force of 0.154 N when theircenter-to-center separation is 42.2 cm. The spheres are thenconnected by a thin conducting wire. When the wire is removed, thespheres repel each other with an electrostatic force of 0.0430 N.Of the initial charges on the spheres, with a positive net charge,what was (a) the negative charge on one of them and (b) thepositive charge on the other? (Assume the negative charge hassmaller magnitude.)
