A beam is turned about a pivot at its centre of mass. Two forces, $10\,\text{N}$ and $5.0\,\text{N}$, act on it, as shown. What is the resultant moment about the pivot?
- A$25\,\text{N cm}$ anticlockwise
- B$25\,\text{N cm}$ clockwise
- C$175\,\text{N cm}$ anticlockwise
- D$175\,\text{N cm}$ clockwise
