Two non-mixing liquids of densities $\displaystyle \rho$ and $\displaystyle \mathrm{n} \rho(\mathrm{n}>1)$ are put in a container. The height of each liquid is $\displaystyle h$. A solid cylinder of length $\displaystyle L$ and density $\displaystyle d$ is put in this container. The cylinder floats with its axis vertical and length $\displaystyle \mathrm{pL}(\mathrm{p}<1)$ in the denser liquid. The density d is equal to :
