Question

{ †ext { Two non-mixing liquids of densities } ρ †ext { and } n _ { p } ( n > } { †ext { 1) are put in a container. The height of each liquid } } { †ext { is } h †ext { solid cylinder of length } L †ext { and density d is } } { †ext { put in this container. The cylinder floats with its } } { †ext { axis vertical and length } p L ( p < 1 ) †ext { in the denser } } { †ext { liquid. The density } d †ext { is equal to } } { †ext { (1) } \{ 1 + ( n - 1 ) p \} ρ } { †ext { (2) } \{ 2 + ( n + 1 ) p \} _ { 0 } } { †ext { (4) } \{ 2 + ( n - 1 ) p \} _ { 0 }
