If the shape of the liquid surface is curved, then the
Show Hint
A curved liquid surface has excess pressure on its concave side.
Updated On: Nov 13, 2026
pressure on the convex side is equal to the atmospheric pressure.
pressure on the convex side is equal to the pressure on the concave side.
pressure on the concave side is greater than that on the convex side.
pressure on the concave side is lesser than that on the convex side.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Surface tension makes a curved liquid surface behave like a stretched membrane.
Step 2: Excess pressure
The pressure is always higher on the concave side than on the convex side of the surface.
Step 3: Compare the options
Equality of pressures or a lower pressure on the concave side is not possible for a curved surface.
Final Answer:
The pressure on the concave side is greater than that on the convex side. \[ \boxed{\text{(C) }\text{pressure on the concave side is greater than that on the convex side.}} \]
