A)
Height of the liquid in the tube A is maximum
B) Height of the liquid in the tubes A and B is the same
C) Height of the liquid in all the three tubes is the same
D) Height of the liquid in the tubes A and C is the same
Correct Answer: D
Solution :
As cross-section areas of both the tubes A and C are same and tube is horizontal. Hence according to equation of continuity \[{{v}_{A}}={{v}_{C}}\] and therefore according to Bernoulli's theorem \[{{P}_{A}}={{P}_{C}}\]i.e. height of liquid is same in both the tubes A and C.
