If a¯=7i^−4j^−4k^ and b¯=−2i^−j^+2k^ then vector c¯ along the bisector of a¯ and b¯ so that |c|=56 is

Any vector along bisector is λ(a¯|a¯|+b¯|b¯|)

An Intiative by Sri Chaitanya

$\frac{5}{3} (- \hat{i} - 7 \hat{j} - 2 \hat{k})$

$\frac{5}{3} (\hat{i} + 7 \hat{j} + 2 \hat{k})$

$\hat{i} - \hat{j} + \hat{k}$

$\frac{5}{3} (\hat{i} - 7 \hat{j} + 2 \hat{k})$
