A small metal bead, labeled A, has a charge of 27 nC . It is touched to metal bead B, initially neutral, so that the two beads share the 27 nC charge, but not necessarily equally. When the two beads are then placed 5.0 cm apart, the force between them is 4.5×10−4 N . Assume that A has a greater charge. What is the charge qA and qB on the beads? Express your answer in nanocoulombs.
Conservation of charge gives us
The force between these two charges at distance 4 cm apart is given by
From the first equation
The solutions to this quadratic equation are
and
We know
Which gives us
