Question

the volume of the hollow portion of a sphere is 3/4 of the external
volume of the sphere If it floats in a liquid of relative density
/2, half of its external volume immersed, then calculate relative
density of the material of the solid?

Dear Student,

relative density of solid, ρ1=?relative density of liquid, ρ2=32V1-34ρ1g=V2ρ2gV4ρ1g=V2×32gρ1=3
