Write the equation of excess pressure for a liquid drop.
(N/A) For a liquid drop,there is only one free surface. The excess pressure $P$ inside a liquid drop of radius $R$ and surface tension $T$ is given by the formula:
$P = \frac{2T}{R}$
where:
$P$ is the excess pressure,
$T$ is the surface tension of the liquid,
$R$ is the radius of the liquid drop.
$P = \frac{2T}{R}$
where:
$P$ is the excess pressure,
$T$ is the surface tension of the liquid,
$R$ is the radius of the liquid drop.
