Block Suspended in Liquids at Different Depths---Buoyant Force

Shown below are six objects that have different masses and different volumes. These blocks are suspended at two different depths in water by being hung by a string from a supporting rod. Rank these situations, from greatest to least, on the basis of buoyant force on the blocks by the water. Greatest Force 1 2 3 4 5 6 Least Force Or, all of the buoyant forces on the blocks by the water are equal. Or, there are no buoyant forces on the blocks by the water. Or, it is not possible to determine the buoyant forces on the blocks by the water. Please carefully explain your reasoning.

Explanation / Answer

The buoyant force is by DEFINITION the force equal to the weight of the displaced fluid. It does not depend on the mass of the object nor on the depth where it is submerged. It depends only in its volume. Greter the volume, greater the buoyant force. (Weight = ro(liquid)*Volume*g)
