170) Comparing the values of
paring the values of loss in weight of all three blocks (W, - W,) in water and the
weight of the displaced water, draw a suitable conclusion.
hervation : Least count of the spring balance = ...... g.wt.
Weight of Weight of Loss in weight

Conclusion/Inference : The loss in weight of the body in water is equal to the weight of the
water displaced by the body when it is immersed in the water. When an object is partially or
fully immersed in a fluid, a force of buoyancy acts on it in the upward direction. This force
Is equal to the weight of the fluid displaced by the object.
Note . The ho forces mentioned here are egual magnitude and opposite in direction​

Answer 1

Answer:

It is based on the principle of arcimedes

that when a body is partially or completely immersed in a liquid it experiences an upthrust or buoyant whose magnitude is equal to the weight of the body
