Question

Derive an expression of excess pressure inside a liquid drop​

Answer 1

Answer:

The surface tension force downward around circle is equal to the surface tension of the circumference, since only one surface contributed to the force : Thus, Fdownward=T(2πr) where, T= surface tension. This gives, P1−P0=r2T which represents theexcess pressure inside the liquid drop.
