1.	Let →a=^i+^j+^k,→b and →c=^j−^k be three vectors such that →a×→b=→c and →a⋅→b=1. If the length of projection vector of the vector→b on the vector →a×→c is l, then the value of 3l2 is equal to
Answer» Let $\to a =^i +^j +^k, \to b$ and $\to c =^j -^k$ be three vectors such that $\to a \times \to b = \to c$ and $\to a \cdot \to b = 1$ . If the length of projection vector of the vector $\to b$ on the vector $\to a \times \to c$ is $l$ , then the value of $3 l^{2}$ is equal to
