Figure shows a capillary tube `C` dipped in a liquid that wets it. The liquid rises to a point `A`. If we blow air through the horizontal tube `H`, what will happen to the liquid column in the capillary tube?

A

level will rise above A

B

level will fall below A

C

level will remain at A

D

remain at the same level

Text Solution

Verified by Experts

The correct Answer is:
A
Level will rise because to compensate for the reduction in pressure above A, due to high velocity (from Bernoulli's principle pressure decreases if velocity increases.)
