Two identical cyclindrical vessels (area of cross section 3.5 xx 10^(-3) m^(2)) with their bases at the same level contain liquid of density 800 kg//m^(3). The height of liquid in one vessel is 0.3 m and in the other it is 0.1 m. Assuming g = 10 m//s^(2),find the workdone by gravity in equalising levels when the vessels are interconnected at bottom.

1.	Two identical cyclindrical vessels (area of cross section 3.5 xx 10^(-3) m^(2)) with their bases at the same level contain liquid of density 800 kg//m^(3). The height of liquid in one vessel is 0.3 m and in the other it is 0.1 m. Assuming g = 10 m//s^(2),find the workdone by gravity in equalising levels when the vessels are interconnected at bottom.
