Text Solution

Verified by Experts

The correct Answer is:
C
The excess pressure inside the small drop is large as compared to the large drop because of which smaller drop of liquid resists deforming force better than the large drop.
Excess pressure=`(2T)/(r)`
Where T=surface tension
r=radius of liquid drop.
Therefore excess pressure is inversely proportional to its radius and hence the surface area.

Statement-1: Two identical conincal pipes shown in figure have a drop of water. The water drop tens to move towards tapered end. Statement-2: Excess pressure is directed towards centre of curvature and inversely proportional to radius of curvature. Net excess pressure is therefore, directed towards tapered end. So the water drop tends to move towards tapered end.
