JEE MainMathematicsVector AlgebraNumerical+4 / −1
Let a⃗=i^+2j^+3k^\vec{a}=\hat{i}+2 \hat{j}+3 \hat{k}a=i^+2j^​+3k^ and b⃗=i^+j^−k^\vec{b}=\hat{i}+\hat{j}-\hat{k}b=i^+j^​−k^. If c⃗\vec{c}c is a vector such that a⃗⋅c⃗=11,b⃗⋅(a⃗×c⃗)=27\vec{a} \cdot \vec{c}=11, \vec{b} \cdot(\vec{a} \times \vec{c})=27a⋅c=11,b⋅(a×c)=27 and b⃗⋅c⃗=−3∣b⃗∣\vec{b} \cdot \vec{c}=-\sqrt{3}|\vec{b}|b⋅c=−3​∣b∣, then ∣a⃗×c⃗∣2|\vec{a} \times \vec{c}|^{2}∣a×c∣2 is equal to ‾\underline{\hspace{2cm}}​.
