Answer
$\textbf{m}$ and $\textbf{p}$ equal $2\textbf{t}$
$\textbf{m}$= $1\textbf{p}$ and $\textbf{n}$=$1\textbf{r}$.
Work Step by Step
According to the requirements of the term 'positive scalar', we need to identify pairs of vectors that may have different magnitudes but should be in the same direction. According to this definition, the required pair of vectors are $\textbf{m}$ and $\textbf{p}$ equal $2\textbf{t}$,
$\textbf{m}$= $1\textbf{p}$ and $\textbf{n}$=$1\textbf{r}$.
