Question

A ball floats with 1/3rd of its volume outside water and 3/4th of its volume outside liquid then the density of liquid is :
(A) 3/8 g/cm^3
(B) 8/3 g/cm^3
(C)9/4g/cm^3
(D) 4/9 g/cm^3
plz answer step by step​

Answer 1

according to archimedes law the buoyant force is equal to the mass displaced by the body . thus buoyant force is equal to the mass of the body then let relative density be 'p'

2/3v=1/4vp (v is the volume of the body)

( relative density of water is 1)

hence p = 8/3g/cm^3
