The diagram represents a uniform beam $PQ$. Its length is $3.0\,\text{m}$ and its weight is $50\,\text{N}$. The beam rests on a pivot that is $1.0\,\text{m}$ from end $P$. A load with weight $W$ is attached at end $P$. The beam is balanced in equilibrium. What is the value of $W$?
- A$25\,\text{N}$
- B$50\,\text{N}$
- C$75\,\text{N}$
- D$100\,\text{N}$
