Question

A small metal bead, labeled A, has a charge of 26 nC . It is touched to metal bead B, initially neutral, so that the two beads share the 26 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?
Answer in two significant figures and unit nC.

Answer 1

qA = 13 nC, qB = 13 nC
