Consider two identical dipoles $\displaystyle \mathrm{D}_{1}$ and $\displaystyle \mathrm{D}_{2}$. Charges -q and q of dipole $\displaystyle \mathrm{D}_{1}$ are located at $\displaystyle (0,0)$ and $\displaystyle (\mathrm{a}, 0)$ and that of dipole $\displaystyle \mathrm{D}_{2}$ at ( $\displaystyle 0, \mathrm{a}$ ) and ( $\displaystyle 0,2 \mathrm{a}$ ) in $\displaystyle x$-y plane, respectively. The net dipole moment of the system is
