A simple pendulum is carried at a depth of 1 km below sea level. It becomes
slow
unchanged
fast
none of these
T=√1g(1−δρ)′ δ= fluid density, ρ= density of pendulum material
Calculate the pressure at a depth of 100m below the surface of the sea. The density of sea water is 1024kgm3.
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)
