Two identical conducting spheres,fixed in place ,attract each other with an electrostatic force of 0.108 N when their centre to centre 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 0.0360 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)the positive charge on the other ?

Where the superscript means initial and final.
Also Since connected by a wire

We will get a quadratic equation now.
You can easily solve that.
