An iceberg floats in fresh water with a part of it outside the water surface. Find the fraction of the volume of the iceberg which is below the water surface.
Take density of ice = 917 kg m⁻³ and density of fresh water = 1000 kg m⁻³

If the iceberg floats smoothly, then the weight is equal to the buoyancy force.
w=Bmig=mwgρiVi=ρwVsVsVi=ρiρwVsVi=918kg/m31000kg/m3=0.918VsVi=0.918w=Bmig=mwgρiVi=ρwVsVsVi=ρiρwVsVi=918kg/m31000kg/m3=0.918VsVi=0.918
The fraction of ice below the water surface is 0.918
