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= `3 xx` density of the water= 3 g `cm^(-3)`
