An electric dipole of moment $\displaystyle \overrightarrow{\mathrm{p}}=(-\hat{i}-3 \hat{j}+2 \hat{k}) \times 10^{-29} \mathrm{C.m}$ is at the origin $\displaystyle (0,0,0)$. The electric field due to this dipole at $\displaystyle \overrightarrow{\mathbf{r}}=+\hat{i}+3 \hat{j}+5 \hat{k}$ (note that $\displaystyle \vec{r} \cdot \vec{p}=0$ ) is parallel to :
