Question

When a body is immersed in a fluid, partially or completely, the force of buoyancy is equal to_____________

• A. the weight of the volume of the fluid equal to the volume of the body
• B. the product of the weight of the body and acceleration due to gravity.
• C. the weight of the body.
• D. The weight of of the fluid displaced by the body

Answer 1

Answer:

A. the weight of the volume of the fluid equal to the volume of the body

When an object is submerged in a fluid, it experiences a buoyant force which is equal to the weight of the fluid displaced by the object. This is known as the Archimedes principle, and the buoyant force acts vertically upwards through the centroid of the displaced volume.
