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 on it?

Question

Quizplus · Accepted Answer

The buoyant force depends on the volume of the object submerged in the fluid. Since aluminum is less dense than lead, for the same mass, the aluminum piece will have a larger volume and thus experience a greater buoyant force.
