Gce Model Questions Vol1 2020 Physics Question 11
Practice objective / multiple choice question 11 from the 2020 Gce Model Questions Vol1 Physics examination.
A U‑tube manometer contains water in the left leg and mercury in both legs. The water column in the left leg rises \(0.20\,\text{m}\) above the mercury surface in that leg. The mercury surface in the right leg is lower than that in the left leg by an unknown amount \(\Delta h\). (a) Determine \(\Delta h\). (b) If a point \(P\) is located \(0.40\,\text{m}\) below the mercury surface in the right leg, calculate the absolute pressure at \(P\), taking atmospheric pressure as \(1.0\times10^{5}\,\text{Pa}\).
