Q1. An electric field is set up between two parallel plates, each of area 2.2 m2, by putting 1.0 C charge on one plate and the -1.0 C charge on the other. The plates are separated by 4.0 mm. What is the magnitude of the electric field between the plates at a distance of 1.0 mm from the positive plate?

Q2. A small metal bead, labelled A, has a charge of 28 nC. It is touched to metal bead B, initially neutral, so that two beads share the 28 nC charge, but not necessarily equally. When the two beads are then positioned 6.0 cm apart, the force between them is 4.6x10^-4 N. imagine that A has a greater charge. What is the charge q_A and q_B on beads?
