Two identical cylindrical vessels, each of base area A, have their bases at the same horizontal level. They contain a liquid of density 
. In one vessel, the height of the liquid is 
and in the other 
. When the two vessels are connected, the work done by gravity in equalising the levels is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Common height after they are connected can be determined by equating the volumes, hence
The decrease in height 
Mass of liquid in 
column, 
Work done by gravity
