Detailed Solution

The given statement is false.

According to Archimedes’ principle, when a body is immersed fully or partially in a liquid, it experiences an upward force that is equal to the weight of the liquid displaced by it.
The upward force exerted by the liquid on the body is known as upthrust or buoyant force.
An object immersed in water is subjected to mainly two forces, gravitational force or the weight of an object acting downwards and the buoyant force acting upwards.
The object floats when the buoyant force exerted by water is more than the weight of the object and the object sinks when the buoyant force is less than the weight of the object.

Therefore, the correct statement would be: An object floats on water when the weight of the object is less than the buoyant force exerted on it.
