Two blocks with the same weight but different dimensions are floating in water at different levels.
Block A is as tall as block B but is smaller in both other dimensions.

A B Is the buoyant force exerted by the water on block A () greater than, (ii) less than, or (ii) equal to the buoyant force on block B?

Explain your reasoning.

Answer:

(ii) less than

Explanation:

The blocks has the same mass. So, the buoyant force depends only on the volume of the displaced fluid. Since block A has a smaller volume than block B, it displaces a smaller amount of fluid. Therefore the bouyant force exerted by water is less in block A than in block B.
