Question

Three points $O$, $P$ and $Q$ are such that $\vec{OP}=-2\mathbf{p}$ and $\vec{OQ}=3\mathbf{q}$. Express $\vec{PQ}$. Another point $R$ is such that $\vec{QR}=2\mathbf{q}-3\mathbf{p}$, find $\vec{OR}$ in terms of $\mathbf{p}$ and $\mathbf{q}$.

Accepted Answer

(a) PQ = 2p + 3q. (b) OR = 5q - 3p.
