A deep-sea research submersible is operating at a constant depth where the external water pressure is uniform. One viewport (window) has a smaller surface area than a second viewport on the same submersible.
Explain how the force exerted by the water pressure on the smaller viewport compares to the force on the larger viewport.
54 exam-style questions on Edexcel GCSE Physics 15.2 Pressure in fluids, covering 15.2.1 Atmospheric pressure and height, 15.2.2 Pressure in fluids, 15.2.3 Pressure, force and area, 15.2.4 Pressure and depth, 15.2.5 Pressure in liquids: depth and density, 15.2.6 Upthrust, and 15.2.7 Floating and sinking. Each one has a worked solution and a mark scheme showing where the marks go.
