A 10-kg piece of aluminum sits at the bottom of a lake,right next to a 10-kg piece of lead,which is much denser than aluminum.Which one has the greater buoyant force exerted on it by the water?
A)the aluminum
B)the lead
C)The same buoyant force is exerted on both.
D)It cannot be determined without knowing their volumes.

Question

The buoyant force depends on the volume of fluid displaced. Since aluminum is less dense than lead, a 10-kg piece of aluminum will have a larger volume than a 10-kg piece of lead, displacing more water and thus experiencing a greater buoyant force.
