Two point charges placed in air separated by distance $R$ exert a force $F$ on each other. Now the space between those charges is filled with dielectric constant $K$. At distance $R_1$ between the charges, the same force is exerted as $F$. Then

$R_1 = \sqrt{K}R$

$R_1 = R$

$R_1 = \dfrac{R}{K}$

$R_1 = \dfrac{R}{\sqrt{K}}$
