this is Archimedes' Principle
This phenomenon is known as buoyancy, which is a force exerted by a fluid that opposes the weight of an object immersed in it. The buoyant force is equal to the weight of the fluid displaced by the object. As a result, the object effectively weighs less when submerged in the fluid.
When an object is placed in water, it displaces an amount of water equal to its own weight. If this displaced water weighs more than the object, the object will float. This is because the buoyant force pushing up on the object is greater than the force of gravity pulling it down.
According to Archimedes principle...An object immersed in water experiences a force equal to the weight of the volume of liquid displaced by it. Here the weight of liquid displaced is 15n. So, the upward buoyant force experienced by that object is 15n.
An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
No. The amount an object weighs is simply called its "weight".

It sinks. (the object weighs more than the water displaced.)
