The diagram depicts a dam that is retaining water behind it. The water has a depth of $65\,\text{m}$. The water density is $1000\,\text{kg m}^{-3}$. The gravitational field strength $g$ is $10\,\text{N kg}^{-1}$. What pressure is produced at the foot of the dam by the water?
- A$15.4\,\text{Pa}$
- B$154\,\text{Pa}$
- C$65\,000\,\text{Pa}$
- D$650\,000\,\text{Pa}$
