Explanation:
Work done by gravity is given by the formula,
            W =  ......... (1)
 ......... (1)
It is known that when levels are same then height of the liquid is as follows.
            h =  ......... (2)
 ......... (2)
Putting value of equation (2) in equation (1) the overall formula will be as follows.
        W = 
            = 
            = 0.689 J
Thus, we can conclude that the work done by the gravitational force in equalizing the levels when the two vessels are connected is 0.689 J.
