A flat, circular optical sensor window on a deep-sea research probe has a surface area of 0.024 m2.
At a certain depth, the hydrostatic pressure of the seawater acting on the window is 4.5 MPa (4.5 × 106 Pa).
Calculate the magnitude of the force exerted by the seawater on the window.
Use the equation:
pressure=forcearea \text{pressure} = \frac{\text{force}}{\text{area}} pressure=areaforce54 exam-style questions on Edexcel GCSE Physics 15.2 Pressure in fluids (physics only). Each one has a worked solution and a mark scheme showing where the marks go.
