IF the surface tension of liquid is 70 dyn/cm, what is the total energy of the free surface of the liquid drop of radius 0.1 cm ?

Explanation

To find the total energy of the free surface of a liquid drop, we can use the formula for the energy associated with the surface tension of a liquid drop:

\[ E = 4 \pi r^2 T \]

Where:
- \(E\) is the total energy of the free surface,
