A water vessel of mass 300kg and volume 900 m3 floats ofn water and while floating a buoyant force of 2.94*10^6 N acts on it. Keeping the volume same, the vessel is tried to use as submerged submarine. What part of the volume of the vessel remains submerged when the vessel was floating on water ?

radius (r)=5cm
1m=100cm
1cm=1/100cm
r in meter 5/100 =1/20 m
v=(4/3)*pi*(r*r*r)
formula of volume for sphaire v=(4/3)*(22/7)*(1/20)*(1/20)*(1/20)
density d=m/v
m=d*v
d=10500 kg/m3

m=2.004545
