A small metal bead, labeled A, has a charge of 28 nC. It is touched to metal bead B, initially neutral, so that the two beads share the 28 nC charge, but not necessarily equally. When the two beads are then placed 5.0cm apart, the force between them is 4.610^-4 N. Assume that A has a greater charge. What is the charge q_A and q_B on the beads?
