$\overrightarrow{\mathbf{P}}=9 \hat{\mathbf{i}}+\hat{\mathbf{j}}-6 \hat{\mathbf{k}}$ এবং $\overrightarrow{\mathbf{P}}=9 \hat{\mathbf{i}}+\hat{\mathbf{j}}-6 \hat{\mathbf{k}}$ হলে-$\begin{array}{l}\text{i. } \overrightarrow{\mathrm{P}} \perp \overrightarrow{\mathrm{Q}}\\\text{ii. } \overrightarrow{\mathrm{P}} \| \overrightarrow{\mathrm{Q}}\\\text{iii. } |\overrightarrow{\mathrm{P}}|=\sqrt{118}\end{array}$
