Question

A body weights 100grms in air 80 grms in a liquid and 75grms in water. The density liquid is​

Answer 1

Answer:

density of liquid is less than that of water

pls mark as brainliest

Answer 2

Explanation:

The weight in water will be

(ρs−ρl)Vg=80gm(ρs−ρl)Vg=80gm

where V is the volume, and s and l denote the object and water respectively. The density in air will be

ρsVg=100gmρsVg=100gm

then you get:

(ρs−ρl)Vg=80100ρsVg(ρs−ρl)Vg=80100ρsVg

then you get:

(ρs−ρl)Vg

=80100ρsVg(ρs−ρl)Vg=80100ρsVg

ρs=5ρl=5000kgm−3ρs=5ρl=5000kgm−3
