If →a=−→i+→j+→k and →b=2→i+→j+→k, then the vector � – InterviewSolution

1.	If →a=−→i+→j+→k and →b=2→i+→j+→k, then the vector →c satisfying the conditions1) coplanar with →a and →b2) perpendicular to →b3)→a⋅→c=7 is
Answer» If $\to a = - \to i + \to j + \to k and \to b = 2 \to i + \to j + \to k,$ then the vector $\to c$ satisfying the conditions $1) coplanar with \to a and \to b$ $2) perpendicular to \to b$ $3) \to a \cdot \to c = 7$ is
