Archimedes principal ---- It states that when an object is immersed in a fluid, fully of partially, it experiences an upward force equal to the weight of fluid displaced by it. The object who have density lesser than water will float on it. That's why cork floats on water.The object who have density greater than water will sink in it. That's why iron nail sinks in water

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.
