1.	Let →a,→b and →c be three non-coplanar unit vectors such that the angle between every pair of them is π3 . If →a×→b+→b×→c=p→a+q→b+r→c, where p,q and r are scalars, then the value of p2+2q2+r2q2 is
Answer» Let $\to a, \to b$ and $\to c$ be three non-coplanar unit vectors such that the angle between every pair of them is $\frac{π}{3}$ . If $\to a \times \to b + \to b \times \to c = p \to a + q \to b + r \to c$ , where $p, q$ and $r$ are scalars, then the value of $\frac{p^{2} + 2 q^{2} + r^{2}}{q^{2}}$ is
