Let \(O\) be the origin, \(\overrightarrow{O P}=\vec{a}\) and \(\overrightarrow{O Q}=\vec{b}\). If \(R\) is the point on \(\overrightarrow{O P}\) such that \(\overrightarrow{O P}=5 \overrightarrow{O R}\), and \(M\) is the point such that \(\overrightarrow{O Q}=5 \overrightarrow{R M}\), then \(\overrightarrow{P M}\) is equal to:
