Pressure — practice question

A washbasin has an outlet pipe that is sealed by a plug with an area of $12\text{ cm}^2$. A chain is fixed to the middle of the plug to make it easier to lift the plug away from the outlet hole. Water in the washbasin is $0.080\text{ m}$ deep. The water has a density of $1000\text{ kg m}^{-3}$. What is the force exerted on the plug by the water?

  • A$0.96\text{ N}$
  • B$800\text{ N}$
  • C$9600\text{ N}$
  • D$80\,000\text{ N}$
