Calculate the pressure at a depth of 50m below the surface of the sea. The density of sea water is 1024 kg/m3.
( Accelaration due to gravity = 10m/s2)
None of these
The expression of pressure at the bottom of a liquid of height ‘h’ and density ‘d’ is given by dgh.
The given values are:
d=1024kg/m3, h=50m and g=10m/s2
Thus, pressure=dgh=1024 × 50 ×10=512000Pa.
