A diver weighing $500\,\text{N}$ is standing at the far end of a springboard that is $2.0\,\text{m}$ long and fixed at point $P$. The springboard itself weighs $500\,\text{N}$. Its centre of mass is located at the midpoint of the board. What is the total moment about point $P$ due to the diver and the board?
- A$500\,\text{N m}$
- B$750\,\text{N m}$
- C$1000\,\text{N m}$
- D$1500\,\text{N m}$
