Pressure — practice question

A swimmer is positioned on the bottom of a pool. The water in the pool has a density of $1000\,\text{kg m}^{-3}$, and the gravitational field strength is $9.8\,\text{N kg}^{-1}$. Which expression gives the pressure exerted on the swimmer by the water?

  • A$\dfrac{5.0 \times 1000}{9.8}\,\text{Pa}$
  • B$5.0 \times 1000 \times 9.8\,\text{Pa}$
  • C$\dfrac{1000}{5.0}\,\text{Pa}$
  • D$\dfrac{1000 \times 9.8}{5.0}\,\text{Pa}$
