A horizontal metal bar PQ with a length of $50.0\,\text{cm}$ is hinged at P. The diagram shows the metal bar as seen from above. At end Q, two forces of $16.0\,\text{N}$ and $5.0\,\text{N}$ act in the horizontal plane, as shown in the diagram. What is the combined moment about P caused by the two forces?
- A$1.5\,\text{N m}$
- B$4.4\,\text{N m}$
- C$6.5\,\text{N m}$
- D$9.4\,\text{N m}$
