The vector \overline{x} is perpendicular to the vectors \overline{a}=3 \overline{i}+2 \overline{j}+2 \overline{k}, \overline{b}=18 \overline{i}-22 \overline{j}-5 \overline{k} and makes an obtuse angle with \overline{j}. If |x|=14, then \overline{x}=

Correct Answer is : −8i−12j+24k

8\overline{i}+12 \overline{j}+24 \overline{k}

-8 \overline{i}+6 \overline{j}+24 \overline{k}

8 \overline{i}-12 \overline{j}-24 \overline{k}

-8 \overline{i}-12 \overline{j}+24 \overline{k}
