A piece a wood of relative density 0.25 floats in a beaker containing oil of relative density 0.81, what fraction of volume of wood above the surface of oil?

Step 1

Let the volume of the wood be V and v is the volume of the mood inside.

The density of the wood is given as r_{1}=0.25

And the density of the oil be r_{2}=0.81

Step 2

Thus from Buoyancy...
