Let →a,→b and →c be three vectors such that |→a|=√3,|→b|=5 – InterviewSolution

1.	Let →a,→b and →c be three vectors such that \|→a\|=√3,\|→b\|=5,→b.→c=10 and the angle between →b and →c is π3. If →a is perpendicular to vector →b×→c, then \|→a×(→b×→c)\| is equal to
Answer» Let $\to a, \to b$ and $\to c$ be three vectors such that $\| \to a \| = \sqrt{3}, \| \to b \| = 5, \to b . \to c = 10$ and the angle between $\to b$ and $\to c$ is $\frac{π}{3} .$ If $\to a$ is perpendicular to vector $\to b \times \to c$ , then $\| \to a \times (\to b \times \to c) \|$ is equal to
