NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): In a vertical capillary tube, the water rises due to capillary action. | Reason (R): The pressure inside the fluid at all points is equal and undiminished.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option B
Detailed Explanation
The water rises in a capillary tube due to surface tension and the contact angle, not because of pressure uniformity in the fluid. The reason mentioned describes pressure in static fluids, which does not explain capillary rise.
