Question

A body floats in a liquid 1/2 immersed in liquid B two -third immersed in liquid C three fifth immersed . compare the upthrust on the boat three liquids?

Answer 1

• The upthrust on the body by each liquid is same and it is equal to the weight of body. But upthrust=volume  submerged ρl×g. For liquid C, since volume submerged is least so denisty ρ3 must be maximum.
