Two identical cylindrical vessels each of area of cross section A are on a level ground. Each contains a liquid of density rho. The heights of liquid columns are h_(1) and h_(2).If the two vessels are connected by means of a narrow pipe at the bottom, the work done by gravity in equalizing the liquid levels is

1.	Two identical cylindrical vessels each of area of cross section A are on a level ground. Each contains a liquid of density rho. The heights of liquid columns are h_(1) and h_(2).If the two vessels are connected by means of a narrow pipe at the bottom, the work done by gravity in equalizing the liquid levels is
Answer» `(Arhog(h_(1)-h_(2))^(2))/2` `(Arhog)/2(h_(1)^(2)-h_(2)^(2))` `(A rhog)/4(h_(1)^(2)-h_(2)^(2))` `(Arhog)/4(h_(1)-h_(2))^(2)` ANSWER :D
