A metal bar PQ lies horizontally and has a length of $50.0\,\text{cm}$; it is hinged at the end P. The diagram presents the bar as seen from above. At end Q, two forces, one of $16.0\,\text{N}$ and the other of $5.0\,\text{N}$, act in the horizontal plane, as indicated. What is the resultant moment about P caused by these two forces?
- A$1.5\,\text{N m}$
- B$4.4\,\text{N m}$
- C$6.5\,\text{N m}$
- D$9.4\,\text{N m}$
