Two charges $\displaystyle 7 \mu \mathrm{c}$ and $\displaystyle -4 \mu \mathrm{c}$ are placed at ( $\displaystyle -7 \mathrm{~cm}, 0,0$ ) and ( $\displaystyle 7 \mathrm{~cm}, 0,0$ ) respectively. Given, $\displaystyle \epsilon_0=8.85 \times 10^{-12} \mathrm{C}^2 \mathrm{~N}^{-1} \mathrm{~m}^{-2}$, the electrostatic potential energy of the charge configuration is :
