Multiple choice

The fraction of the total volume of an iceberg of density 0.93 floating in North Sea with density of 1.03 gm/cm3 is

  1. 1%

  2. 11%

  3. 21%

  4. 75%

B Correct answer
Explanation

For a floating body, the fraction submerged equals the ratio of densities: fraction_submerged = density_iceberg / density_water. Here: 0.93/1.03 = 0.9029, meaning about 90.29% is submerged. The visible (above water) fraction is 1 - 0.9029 = 0.0971 or 9.71%, which rounds to approximately 11%. Option B is closest.
