Mathematics - 3D Coordinate Geometry Question with Solution | TestHub

Equation of plane passing through the point having position vector $\bar{a}$ and normal to $\overline{\mathrm{n}}$ is $\therefore \overline{\mathrm{r}}\cdot \overline{\mathrm{n}}\cdot (2\hat{\mathrm{i}}+3\hat{\mathrm{j}}-4\hat{\mathrm{k}})=(\hat{\mathrm{i}}-\hat{\mathrm{j}}+\hat{\mathrm{k}})\cdot (2\hat{\mathrm{i}}+3\hat{\mathrm{j}}-4\hat{\mathrm{k}})=2-3-4=-5$
