1.	Let →u be a vector coplanar with the vectors →a=2^i+3^j−^k and →b=^j+^k. If →u is perpendicular to →a and →u⋅→b=24, then \|→u\|2 is equal to
Answer» Let $\to u$ be a vector coplanar with the vectors $\to a = 2^i + 3^j -^k$ and $\to b =^j +^k$ . If $\to u$ is perpendicular to $\to a$ and $\to u \cdot \to b = 24,$ then $\| \to u \|^{2}$ is equal to
