Question

Some students are discussing the forces acting on a 1kg copper brick and a 1kg lead brick resting at the bottom of the ocean. Student one: The buoyant force is greater on the copper brick because it's larger Student two: "The buoyant force is greater on the lead brick because lead is denser than copper." Student three: "The buoyant force is the same on both bricks because they have the same mass." Which student do you agree with and why? A cubical block of aluminum, 50cm on each edge, is at rest on the bottom pool filled with water. The density of aluminum is 2.70 g/cm^3.

Explanation / Answer

2. lead is denser than copper.

both brick are of same mass so volume of copper will be more than of lead.

and Buoyant force = volume submerged x density of fluid x g

brick is submerged completely.

Ans: Student One
