An electric charge $\displaystyle 10^{-6} \mu \mathrm{C}$ is placed at origin $\displaystyle (0, 0)$m of $\displaystyle X-Y$ co-ordinate system. Two points $\displaystyle P$ and $\displaystyle Q$ are situated at $\displaystyle (\sqrt{3}, \sqrt{3}) m$ and $\displaystyle (\sqrt{6}, 0) m$ respectively. The potential difference between the points P and Q will be :
