JEE MainMathematicsVector AlgebraNumerical+4 / −1
Let the three sides of a triangle ABC be given by the vectors 2i^−j^+k^,i^−3j^−5k^2 \hat{i}-\hat{j}+\hat{k}, \hat{i}-3 \hat{j}-5 \hat{k}2i^−j^​+k^,i^−3j^​−5k^ and 3i^−4j^−4k^3 \hat{i}-4 \hat{j}-4 \hat{k}3i^−4j^​−4k^. Let GGG be the centroid of the triangle ABCA B CABC. Then 6(∣AG→∣2+∣BG→∣2+∣CG→∣2)6\left(|\overrightarrow{\mathrm{AG}}|^2+|\overrightarrow{\mathrm{BG}}|^2+|\overrightarrow{\mathrm{CG}}|^2\right)6(∣AG∣2+∣BG∣2+∣CG∣2) is equal to ‾\underline{\hspace{2cm}}​.
