1.	Let AC be an arc of a circle considered in clock wise direction, subtending a right angle at the centre O. The point B divides the arc AC in ratio 1:2 If −−→OA=→a and −−→OB=→b, then vector −−→OC is equal to
Answer» Let $A C$ be an arc of a circle considered in clock wise direction, subtending a right angle at the centre $O .$ The point $B$ divides the arc $A C$ in ratio $1 : 2$ If $- - \to O A = \to a$ and $- - \to O B = \to b,$ then vector $- - \to O C$ is equal to
