Question

show that there is always excess of pressure on the concave side side of a meniscus of a liquid​

Answer 1

Answer:

$⭐ { \huge{ \fcolorbox{red}{purple}{Answer}}}$

Explanation:

There are two forces involved in capillary action which dictate the curvature of the meniscus. ... Naturally if a tube is thin the grip on the sides of the tube pulling the water upwards overcomes the force caused by gravity and pulls the water upwards.

Answer 2

It has no component perpendicular to the horizontal surface. As a result, there is no pressure difference between the liquid side and the vapour side. ... Thus, there is always an excess of pressure on the concave side of a curved liquid surface over the pressure on its convex side due to surface tension.
