    I had a question. If we had the gold chain in the first example partially immersed in water, in such a case when we say weight acting downwards, do we mean the weight of the immersed part of the solid or the whole solid ?

    It means that the portion of chain which is immersed in the liquid(which we call simply the displaced liquid)that portion of the liquid weighs equal to whole weight of the chain.

    an object floats on water whe the buoyant force is equal to the weight of the object but many have a misconception that an object floats when buoyant force is greater than the weight of the object(by the whay which is quiet not wrong to say) *here is an Explaination to this statement*:- when buoyant force acts constantly upards then the object must acclerate all the way up at the surface of the fluid. but when the object reaches the surface of the fluid the magnitude of buoyant force becomes equal to the magnitude of the weight of the object. therefore the object does not further accelerate upward and rests on the surface of the fluid that is the object is now in a state of equilibrium

    Does partially submerged and floating has a difference I'm confused cuz Archimedes priciple says upthrust of a partially submerged object= weight of the liquid displaced but law of flotation says upthrst =weight of the object
