Problem
A body of uniform cross-sectional area A=1 cm2 and of mass density ρ=0.8 g/cm3 floats in a liquid of density ρ0=1 g/cm3 and at equilibrium displaces a volume V=0.8 cm3. Show that the period of small oscillations about the equilibrium position is given by
τ=2πV/gA
where g is the gravitational field strength. Determine the value of τ.
