(d) A large ship can float but a steel needle sinks, this concept is explained by Archimedes principle which states that when a body is fully or partly all submerged in a fluid, a buoyant force from the surrounding fluid acts on the body. The force is directed upward and has a magnitude equal to the weight of the fluid that has been displaced by the body.
