Buoyant force comparison on two solid objects with equal volume.
Classical Mechanics
Level
3
Two solid objects of the same volume are placed in water. Object A floats and Object B sinks.
The buoyant force on Object A is smaller than on Object B.
The buoyant force on Object A is the same as Object B.
There is not enough information to conclude how the buoyant forces compare.
The buoyant force on Object A is larger than on Object B.

Since the buoyant force is equal to the weight of the water displaced, the floating object will have a lower buoyant force because it is not fully submerged. The object that sunk displaces its entire volume so the weight of the water displaced is more.
