JEE Main 2026 — 22 January, Morning Shift — Question 32
Given below are two statements:
Statement I: Pressure of fluid is exerted only on a solid surface in contact as the fluid-pressure does not exist everywhere in a still fluid.
Statement II: Excess potential energy of the molecules on the surface of a liquid, when compared to interior, results in surface tension.
In the light of the above statements, choose the correct answer from the options given below.
- Option A:
Statement I is true but Statement II is false
- Option B:
Both Statement I and Statement II are false
- Option C:
Both Statement I and Statement II are true
- Option D:Correct
Statement I is false but Statement II is true
Answer: D
Step-by-step solution
According to pascal's law pressure at any point in liquid at rest is same in all direction. It exist at every point in the liquid not just at boundaries. So statement (1) is false. For interior molecule net cohesive forces are zero statement (2) is correct.
