Buoyancy – floating in two immiscible liquids

2016 1 question

1. 1 Mechanical Properties of Fluids Medium
   Two non-mixing liquids of densities $\rho$ and $n\rho$ (n > 1) are put in a container. The height of each liquid is h. A solid cylinder of length L and density d is put in this container. The cylinder floats with its axis vertical and length pL (p < 1) in the denser liquid. The density d is equal to
   A $\{2 + (n + 1)p\}\rho$ B $\{2 + (n - 1)p\}\rho$ C $\{1 + (n - 1)p\}\rho$ D $\{1 + (n + 1)p\}\rho$
