The Buoyant Force

Which of the following statements is true about the buoyant force on an object that is floating on the surface of a lake?

• The buoyant force is greater than the weight of the object.

• The buoyant force is equal to the weight of the fluid displaced.

• The buoyant force is the same as when the object is completely submerged.

• The buoyant force is less than the density of the water.
