Question

Two bodies with volumes V and 2V are equalized on a
balance The larger body is then immersed in oil of densityr= 0 9
g/cc What must be the density of the liquid in which the smaller
body is simultaneously immersed so as not to disturb the
equilibrium of the balance?

The reduction of weight after immersing in liquid is =2V×0
9×gif the smaller has to immerse in liquid of density ρthen loss of weight =V×ρ×gso Vρg =2V×0
9×gρ=1 8 g/cc

Two bodies with volumes V and 2V are equalized on a balance. The larger body is then immersed in oil of densityr= 0.9 g/cc. What must be the density of the liquid in which the smaller body is simultaneously immersed so as not to disturb the equilibrium of the balance?
