Archimedes’ principle states that, when an object is fully or partially immersed in a liquid, it experiences a buoyant force or upthrust, which is equal to the weight of liquid displaced by the object, i.e.Buoyant force or upthrust acting on an object= Weight of liquid displaced by the object.
A cork floats in the water whereas an iron nail sinks because the density of cork is less than the density of water. This means that the upthrust of water on the cork is greater than the weight of the cork. So, it floats. However, the density of an iron nail is more than the density of water. This means that the upthrust of water on the iron nail is less than the weight of the nail. So, it sinks.

Archimedes' Principle
Explanation:
According to Archimedes' principle, when a body is fully or partially submerged submerged in water, the upward buoyant force that is exerted on a body is equal to weight of the water that the body displaces.
A cork floats in the water whereas an iron nail sinks. The reason behind is that an object will float if its density is less than water but if the density of object is more than water it will sink. Here, the the density of an iron nail is more than the density of water. It means that a cork floats in the water whereas an iron nail sinks.
