Density and Buoyancy Review

Why does the object in the picture sink?

• the buoyant force is greater than the force due to gravity (weight)

• the force due to gravity (weight) is greater than the buoyant force

• the buoyant force and the force due to gravity (weight) are the same

• the density force is greater than the buoyant force

Which of the following are true about the object in the picture?

• the forces are balanced

• the buoyant force is greater

• the force due to gravity is greater

• the object floats

• the object sinks
