If $\overrightarrow{\mathrm{a}}=2 \hat{\mathrm{i}}-\hat{\mathrm{j}}-2 \hat{\mathrm{k}}$ and $\overrightarrow{\mathrm{b}}=6 \hat{\mathrm{i}}+2 \hat{\mathrm{j}}-3 \hat{\mathrm{k}}$ are two vectors such that $\vec{a} \cdot \vec{b}$ is minimum, then $t=$
$8$
$-\frac{1}{4}$
$-\frac{1}{8}$
$4$
Solution
Wrong question as $\mathrm{t}$ is not mentioned in question.
