## Question

### Solution

Correct option is

1/5

Density of ice = 900 kgm–3. Density of sea water = 1125 kgm–3. If V is the total volume of the iceberg and n is the fraction of the volume of the iceberg that appears above the surface of sea water, then the volume of the submerged part of iceberg = (1 – n)V. From the principle of flotation we have

Which gives n = 0.2.
