1.	If →a=−^i+^j+^k and →b=2^i+0^j+^k then the vectors →c satisfying the conditions, (i) that it is coplanar with →a and →b (ii) that it is perpendicular to →b, and (iii) that →a.→c=7, is
Answer» If $\to a = -^i +^j +^k$ and $\to b = 2^i + 0^j +^k$ then the vectors $\to c$ satisfying the conditions, (i) that it is coplanar with $\to a$ and $\to b$ (ii) that it is perpendicular to $\to b$ , and (iii) that $\to a . \to c = 7$ , is
