The floor of an exhibition hall must not be subjected to a pressure greater than 18 000 Pa18\,000\ \mathrm{Pa}18000 Pa. An empty display plinth weighs 1200 N. The area of its base in contact with the floor is 2000 cm2.
Calculate the maximum weight of a sculpture that can be placed on the plinth without exceeding the pressure limit.
132 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.
