A horizontal metal bar PQ of length 50.0 cm is hinged at end P. The diagram shows the metal bar viewed from above. Two forces of 16.0 N and 5.0 N are in the horizontal plane and act on end Q as shown in the diagram. What is the total moment about P due to the two forces?

1. A1.5 N m
2. B4.4 N m
3. C6.5 N m
4. D9.4 N m
