Two cylinders of same cross section area and length L but made of two material of densities $d_{1}$ and $d_{2}$ are connected together to form a cylinder of length 2L. The combination floats in a liquid of density d with a length $\frac{L}{2}$ above the surface of the liquid. If $d_{1} > d_{2}$ then
