Question

Buoyant force exerted by a fluid on a given body is :

• A. equal to the volume of body
• B. equal to the weight of body
• C. equal to the volume of fluid displaced by the body
• D. equal to the weight of fluid displaced by the body

Answer 1

The correct option is D equal to the weight of fluid displaced by the body

Buoyant Force is an upward force exerted by a fluid that opposes the weight of an immersed object. The magnitude of this upward force is given by Archimedes' principle which states that:

When a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it.

So option D is correct.
