A sphere floats in water just submerged as shown in the diagram. If atmospheric pressure is neglected then :-

Answer:

Solution:

Force exerted on lower half

$= ρ g (2 R) Π R^{2} - \frac{1}{3} Π R^{3} ρ g = \frac{5 ρ g Π R ^{3}}{3}$

Force exerted by upper half $\frac{5}{3} ρ pR^{3} g - \frac{4}{3} ρ π R^{3} g = \frac{1}{3} ρ π R^{3} g$ Ratio $= 5$
