We have two different liquids `A` and `B` whose relative densities 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

Options

A. `P` floats in `A` and `Q` sinks in `B`
B. `P` sinks in `A` and `Q` floats in `B`
C. `P` floats in `B` and `Q` sinks in `A`
D. `P` sinks in `B` and `Q` floats in `A`

Answer

C

Explanation

`rhoA=0.75, rho_(P)=0.6`
`rhoB=1.0, rho_(Q)=0.9`
As relative density of `P` is lesser than `B`, so it will float in liquid `B` and as relative density of `Q` is greater than liquid `A` so it will sink, because if denisty of the object is greater than that of the liquid in which it is immersed, then its weight is more than the upthrust and vice versa.
