We have two different liquids A and B whose specific gravities are 0.75 and 1.0 respectively. If we dip solid objects P and Q having relative densities 0.6 and 0.9 in these liquids then

ρA=0.75, ρP=0.6, ρB=1.0 and ρQ=0.9As relative density of P is less than that of B, so it will float in liquid B and as relative density of Q is greater than that of liquid A, so it will sink in A, became if density of object is greater than that of the liquid in which it is immersed, then its weight is more than the upthrust and vice versa.
