Question

Please let me know that is the amount of. Water displaced is equal to the mass of the object ??

Answer 1

It is a theory in class 9th book related to buoyant force which is also known as upthrust. Hit action upward direction opposite to the gravitational force and if the volume of the object is equal to water it is half floating and half image in the water and if it is low from the water it Drowns inside and if it is more than water it floats on the water therefore the water displaced is equal to the mass of the object .
Buoyancy arises from the fact that fluid pressure increases with depth and from the fact that the increased pressure is exerted in all directions (Pascal's principle) so that there is an unbalanced upward force on the bottom of a submerged object.Since the "water ball" at left is exactly supported by the difference in pressure and the solid object at right experiences exactly the same pressure environment, it follows that the buoyant force on the solid object is equal to the weight of the water displaced (Archimedes' principle). Objects of equal volume experience equal buoyant forces.
