  4. D \(\sqrt {\frac{3}{2}} \)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\sqrt {\frac{3}{2}} \)

Step-by-step Solution

Detailed explanation

Vector perpendicular to plane containing the vectors \(\hat{i}+\hat{j}+\hat{k} d \hat{i}+2 \hat{j}+3 \hat{k}\) is parallel to vector \( = \left| {\begin{array}{*{20}{l}} {\hat i}&{\hat j}&{\hat k}\\ 1&1&1\\ 1&2&3 \end{array}} \right| = \hat i - 2\hat j + \hat k\) Required…
