Concept:Archimedes’ principle of floatation states that a floating body displaces its own weight of the fluid in which it floats.
Explanation:For a body to float, the upthrust or buoyant force from the fluid must balance the weight of the body.
The upthrust equals the weight of the fluid displaced by the body.
Therefore, the body floats only when it displaces its own weight of the fluid.
This is not about displacing its own volume or density, and the body still experiences gravity.
As a quick check, if the object’s weight
W is greater than the upthrust
U, the object sinks.
For floating,
W=U, meaning the weight of the displaced fluid equals the body’s weight.
Answer:B. Displaces its own weight of the fluid.
