in the left. If 
and 
. Density of the oil is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
If the pressure at the oil-water interface in the left arm is p, then the pressure in the right arm at the level of the interface will also be p.
In the left arm, 
...(i)
In the right arm, 
...(ii)
Equating Eqs. (i) and (ii), we get
