Question

# A cubical block of ice floating in water has to support a metal piece weighing 0.5 kg. Water can be the minimum edge of the block so that it does not sink in water? Specific gravity of ice = 0.9.

Solution

## Given: Specific gravity of ice, ρice = 0.9 gm/cc Weight of the metal piece, m = 5 kg Density of water, ${\rho }_{w}$ = 103 kg/m3​ Let x be the minimum edge of the ice block in cm. We have: mg + Wice = U Here, U = Upward thrust Wice = Weight of the ice PhysicsHC Verma - IStandard XI
