Two cylindrical vessels of equal cross sectional area of $2{\mathrm{m}}^2$ contain water up to height 10 m and 6 m , respectively. If the vessels are connected at their bottom then the work done by the force of gravity is : (Density of water is $10^3\mathrm{kg}/{\mathrm{m}}^3$ and $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$)
