A force of $4.0\,\text{N}$ is applied to a beam as illustrated. The line of action of the force is at a distance $x$ from a pivot. The moment produced by this force about the pivot is $8.0\,\text{N cm}$. What is the distance $x$?
- A$0.50\,\text{cm}$
- B$2.0\,\text{cm}$
- C$12\,\text{cm}$
- D$32\,\text{cm}$
