I had the same doubt weeks back like yours...
***************************Check This*********************
the energy is the product of the charges divided
by the product of distance and dieletric. If the dielectric is rij, then
then energy is (qi*qj)/(r*r). so, the distance dependence of the interaction
energy is 1/r^2, but the dielectric itself is only 1/r.
