Let $\underset{p}{\rightarrow}$ and $\underset{q}{\rightarrow}$ be the position vectors of the points p and Q respectively with respect to origin O. The points R and S divide PQ internally and externally respectively in the ratio 2: 3. If $\underset{OR}{\rightarrow}$ and $\underset{OS}{\rightarrow}$ are perpendicular, then which one of the following is correct?
