NEET Physics Surface Tension Assertion Reason Question
Assertion (A): The capillary rise of a liquid in a tube is due to surface tension. | Reason (R): The pressure inside the tube at the meniscus is greater than the atmospheric pressure.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion is true as the capillary rise is due to surface tension. The reason is false because the pressure inside the tube at the meniscus is less than atmospheric pressure, not greater.
