Text Solution
Verified by ExpertsThe correct answer is:
D
In a curved surface (such as in a capillary tube or in the case of a droplet), the pressure difference across the curved surface is explained by the Young-Laplace equation, which states that the pressure inside a curved liquid surface is different from the pressure outside due to surface tension.
For a liquid like water, the pressure below the curved water surface (inside the liquid) is less than the pressure above it (which is typically atmospheric pressure). The pressure on the upper side is greater than that on the lower side (due to the curved shape), leading to a capillary pressure that is negative relative to the upper side pressure.
Therefore, the capillary pressure below the curved surface of water is indeed lesser than the upper side pressure.
