A ship is made of iron but still it floats in water. This is
because of its shape. A ship is hollow in the middle. When
it is in water, the entire volume of the ship, including the
hollow portion displaces water to make space for itself. The
volume of water displaced is much more than the volume
of iron in the ship. Therefore, the ship floats in water.
Which of these rules can be deduced from the above
given passage?
A If the upthrust is more than the weight, the body
sinks in water.
B If the weight is more than the upthrust, the body
floats in water.
C If the upthrust is less than the weight, the body
floats in water.
D If the weight is more than the upthrust, the body
sinks in water.

Archimedes principle

Class : Class 9
that's true this is based on Archimedes principle:Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics
