A washbasin has an outlet pipe sealed by a plug with area $12\,\text{cm}^2$. A chain is fastened to the plug’s centre to make it easier to pull the plug clear of the outlet hole. Water in the washbasin is $0.080\,\text{m}$ deep. The density of the water is $1000\,\text{kg m}^{-3}$. What force does the water exert on the plug?
- A$0.96\,\text{N}$
- B$800\,\text{N}$
- C$9600\,\text{N}$
- D$80\,000\,\text{N}$
