An electric dipole of moment $P=\left(-\widehat{i}-3\widehat{j}+2\widehat{k}\right)\times {10}^{-29}C-m$  is at the origin $\left(0,0,0\right)$ . The electric field due to this dipole at $\overrightarrow{r}=+\widehat{i}+3\widehat{j}+5\widehat{k}\left(note\overrightarrow{r}.\overrightarrow{p}=O\right)$  is parallel to

since  $\overrightarrow{r}$ and $\overrightarrow{p}$  are perpendicular to each other therefore point lies on the equatorial plane. Therefore electric field at the point will be anti parallel to the dipole moment.
