$\huge\bf\underline{\red{A}\green{N}\orange{S}\pink{W}\purple{E}\blue{R}}$

Consider a liquid drop of radius R and surface tension T. Due to surface tension, the molecules on the surface film experience the net force in the inward direction normal to the surface. Therefore there is more pressure inside than outside. ... The above expression gives us the pressure inside a liquid drop.
