A block of wood floats in water with (4/...

A block of wood floats in water with `(4//5)th` of its volume submerged. If the same block just floats in a liquid, the density of liquid in `(kg m^(-3))` is

A

1250

B

600

C

400

D

800

Text Solution

Verified by Experts

The correct Answer is:
D

Submerge part = Replaced water
`4/5hrho_(w)=hxxrho_(w)hxxrho_(lamda)`
`therefore" "rho_(lambda)=4/5xxrho_(w)=4/5xx1000`
`rho_(w)=800 kgm^(-3)`
