Gce Model Questions Vol1 2023 Physics Question 31
Practice objective / multiple choice question 31 from the 2023 Gce Model Questions Vol1 Physics examination.
A vertical tube of height 0.50 m is filled with water (density \(1000\,\text{kg\,m}^{-3}\)). A small piston of area \(2.0\,\text{cm}^2\) rests on the water surface. At the bottom of the tube a larger piston of area \(20.0\,\text{cm}^2\) supports a load of \(50\,\text{N}\). The tube is closed at the top and the small piston is pressed down with a force \(F\). Ignoring friction and the masses of the pistons, what is the minimum value of \(F\) required to lift the load? (Take \(g = 9.8\,\text{m\,s}^{-2}\).)
