Question
Two beakers of fluid are open at the top to the air. One contains 0.2 cm of mercury and 1 cm of water. The other only contains water. If the pressure at the bottom of the two beakers is identical, how much water is in the beaker with only water? Use density of water of 1000 kg m-3 and density of mercury of 13600 kg m-3.
