The force between two equal charges placed in a medium at a distance of 9 cm from each other is 16 dyne. On increasing one of the charges by 56 statC, it is found that the distance between the charges must be changed by 3 cm in order to keep the force between them the same Calculate the magnitude of the charges and the dielectric constant of the medium . Given `: 1 C = 3 xx 10^9 statC`.
