A hemispherical bowl just floats without sinking in a liquid of density 1.2 x 103kg/m3. If the outer diameter and the density of the bowl are 1 m and , respectively, then the inner diameter of the bowl will be
Weight of the bowl = mg
where D = Outer diameter
d = Inner diameter
= Density of bowl
Weight of the liquid displaced by the bowl
where is the density of the liquid.
