A hemispherical bowl just floats without sinking in a liquid of density . If outer diameter and the density of the bowl are 1 m and 2 x respectively, then the inner diameter of the bowl will be
Weight of the bowl = mg
=
Where D = outer diamter,
d = Inner diameter
= Density of bowl
Weight of the liquid displaced by the bowl
=
where is the density of the liquid.
For the flotation
By solving we get d = 0.98 m.
