At a depth of 1000 m in an ocean (a) What is the absolute pressure ? (b) What is the gauge pressure ? © Find the force acting on the window of area `20cmxx20cm` of a submarine at this depth the interior of which is maintained at sea level atmospheric pressure. (the density of sea water `=1.03xx10^(3)xx10^(3)kgm^(-3),g=10ms^(-2))`
