Text Solution

Verified by Experts

The correct Answer is:
C
From the formula,
Express pressure `= 2T//r`,
Here, `T` is surface tension, `r` is the radius of liquid drop. Hence, excess pressure is inversely proportional to radius and hence the surface, area. Therefore, the excess pressure inside a smaller drop is larger as compared to the larger drop due to which smaller drop of liquid resists deforming forces better than a larger drop.

Statement I: Smaller drops of liquid resist deforming forces better than the larger drops. Statement II: Excess pressure inside a drop is directly proportional to its surface area.

Statement I: Smaller drops of liquid resist deforming forces better than the larger drops. Statement II: Excess pressure inside a drop is directly proportional to its 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.
