Gce Model Questions Vol1 2025 Physics Question 42
Practice objective / multiple choice question 42 from the 2025 Gce Model Questions Vol1 Physics examination.
A U‑shaped tube is open to the atmosphere at both ends. The water in the left leg is \(0.80\) m higher than in the right leg. The cross‑sectional area of the left leg is \(2.0\times10^{-3}\) m\(^2\) and that of the right leg is \(1.0\times10^{-3}\) m\(^2\). Atmospheric pressure is \(1.01\times10^{5}\) Pa. (i) Find the gauge pressure at the bottom of the left leg. (ii) A circular valve of radius \(5\) cm closes the left leg at its bottom; calculate the net force exerted on the valve by the water.
