1.	Let →a,→b,and →c be three unit vectors such that →a×(→b×→c)=√32(→b×→c).If →b is not parallel to →c, then the angle between →a and →b is :
Answer» Let $\to a, \to b, a n d \to c$ be three unit vectors such that $\to a \times (\to b \times \to c) = \frac{\sqrt{3}}{2} (\to b \times \to c) . I f \to b$ is not parallel to $\to c$ , then the angle between $\to a a n d \to b$ is :
