JEE Main 2024 Physics question
Given below are two statements: Statement I: The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well. Statement II: The rise of a liquid in a capillary tube does not depend on the inner radius of the tube. In the light of the above statements, choose the correct answer from the options given below:
Answer: (C)
Solution
The contact angle depends on the solid–liquid pair; the capillary rise h = 2T cos θ/(rρg) depends on the radius.
