A siphon in use is demonstrated in the following figure. The density of the liquid flowing in siphon is 1.5 gm/cc. The pressure difference between the point P and S will be

A
105N/m
B
2 × 105N/m
C
Zero
D
Infinity
Answer
Zero
Explanation
Solution
As the both points are at the surface of liquid and these points
are in the open atmosphere. So both point possess similar
pressure and equal to 1 atm. Hence the pressure difference
will be zero.
