Question 1 (1 points) 1 . A small metal bead. labeled A, has a charge of 28nC. It is touched to metal bead B, initially neutral, so that the two beads share the 28nC charge. but not necessarily equally. When the two heads are then ptaced 5.0 cm apart, the force between them is 5 x 10'4N. Assume that A has a greater charge. Now what is the charge qA on the head A?
