Neco 2021 Physics Question 14
Practice objective / multiple choice question 14 from the 2021 Neco Physics examination.
A rectangular tank 2.0\,m wide and 1.5\,m high is filled with water. A small hole of area \(2.0\times10^{-4}\,\text{m}^{2}\) is made at a depth \(h\) below the water surface. Water exits the hole and strikes a vertical plate placed 0.5\,m horizontally from the hole. If the force exerted on the plate by the jet is 150\,N, determine the depth \(h\) (in metres) of the hole. Use \(g=9.8\,\text{m s}^{-2}\) and \(\rho_{\text{water}}=1000\,\text{kg m}^{-3}\). Give your answer to two decimal places.
