A body weight 20 N in water and 30 N in ...

A body weight 20 N in water and 30 N in air. Find the density of the body. Take the density of water as `1.0 g cm^(-3)`.

Text Solution

Verified by Experts

Let `W_(1) " and" W_(2)` be the weights of the body in air and in water, respectively. Then `W_(1)=30 N " and" W_(2)=20 N`
relative density of the body`=(W_(1))/(W_(1)-W_(2))=3`
`therefore` Density of the body `=3xx` density of the water `=3 g cm^(-3)`
