Concept

Problem: If two identical conducting spheres are in contact, any excess charge will be evenly distributed between the two. Three identical metal spheres are labeled A, B, and C. Initially, A has charge q, B has charge -q/2, and C is uncharged.Starting again from the initial conditions, what is the charge on each sphere if C is touched to A, removed, then touched to B?Express your answer in terms of q.

QA = q

QB = -q/2 

QC = 0

When A and C are put together, the charge on each sphere is:
