A uniform solid cylinder of density $0.8 \mathrm{g} {\mathrm{cm}}^{-3}$ floats in equilibrium in a combination of two non-mixing liquids $\mathrm{A}$ and $\mathrm{B}$ with its axis vertical. The densities of the liquids $\mathrm{A}$ and $\mathrm{B}$ are $0.7 \mathrm{g} {\mathrm{cm}}^{-3}$ and $1.2 \mathrm{g} {\mathrm{cm}}^{-3}$, respectively. If the height of liquid $\mathrm{A}$ is ${\mathrm{h}}_{\mathrm{A}}=1.2 \mathrm{cm\; and\; t}$he length of the part of the cylinder immersed in liquid $\mathrm{B}$ is $0.8 \mathrm{cm}$, then the force exerted by the liquid $\mathrm{A}$ on the cylinder is
