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?

Question

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) It is difficult to predict

The air through the horizontal tube will decrease the pressure and more liquid will be pushed into the capillary tube.

Q. 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?

Level will rise above $A$

Level will fall below $A$

Level will remain at $A$
