In a precision high-pressure laboratory micro-syringe, a linear actuator exerts a force of 18.4 N onto a tiny plunger. This generates a pressure of 1.15 × 107 Pa within the hydraulic fluid.
Calculate the cross-sectional area of the plunger. Give your answer in standard form and include the appropriate unit.
Practise AQA GCSE Physics Pressure and pressure differences in fluids (physics only) with exam-style questions for Foundation and Higher tier. 27 questions covering Pressure in a fluid and Atmospheric pressure, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
