    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 ?

    • @xrdarken-raj4073
      @xrdarken-raj4073 Před 5 měsíci +1

      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.

    Density of the object must be smaller than the density of water for it to float.
    Sir you explained very well the concept of buoyancy and density, Thankyou sir Mahesh!

  • @swapanmallik983
    @swapanmallik983 Před 10 měsíci +2

    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

    • @faizfarhan8231

    If we used an object with the same density force as water, how does the object act? Eg. Could a human push it lower and have the object stationary there, or would it always raise to the surface

    • @eifabeeekhan4571

      no it wont rise up as bouyant force is same as that of weight of obj , so it will remain at the same place where you left

    • @Vabadrish
      @Vabadrish Před dnem

      Suppose you leave the object which is supposed to float ( buoyant force is greater than weight of object) under the water
      There upward (buoyant) force is greater than downward(weight) force
      As soon as you leave the object, it will accelerate upwards and will jump out of the water level becoz of acquired velocity
      (Practically , becoz of surface tension,air drag final result might differ but let's keep it simple for you to understand)
