Question

A 50-cm^3 block of wood is floating partially submerged in water, and a 50-cm^3 block of iron is totally submerged in water. Which block has the greater buoyant force on it? Gustify) A) The wood B) The iron C) Both have the same buoyant force. D) The answer cannot be determined without knowing the densities of the blocks.

Answer 1

Answer:

B) The iron

Explanation:

Both blocks have the same volume. Since the wood is partially submerged, it displaces a smaller volume of fluid than the iron, that is completely submerged. The buoyant force is proportional to the volume of the displaced fluid. Therefore, the buoyant force on iron is greater.
