A long u tube is filled with a liquid of density ‘ ρ ’ such that length of tube above liquid is ‘a’ in both arm. One side of tube (right arm) is sealed the tube is inverted (‘P 0 ’ atmospheric pressure)
A
Liquid will spill out the left tube if a < 
B
Liquid will not spill out the left tube for any value of ‘a’
C
Liquid surface in left arm will not move if a = 
D
Liquid surface in right arm will come down
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, c)
Let pressure of gas in right arm in inverted position be ‘P’.
∴ P (a + x) = P 0 . a …(i)
P + 2x ρ g = P …(ii)
From (i) and (ii)
x =
