An electric charge A of strength 'q' exerts a force'F' on another similar charge B of strength 'q' separated by a distance 'r' in air.

(a) If a third charge C of strength '2q' is placed midway between the charges A and B, what is the force exerted by A on B?

(b) If the magnitude of each charge A and B is doubled and the charges are placed in a medium of relative permitivity 16, at a distance 1/2r, determine the force exerted by A on B?
