A certain number of spherical dropes of a liquid of radius r coalesce to form a single drop of radius R and volume V. If T is the surface tension of the liquid, then

Options

(a) energy =4VT (1/r-1/R) is released
(b) energy =3VT(1/r+1/R) is absorbed
(c) energy = 3VT (1/r-1/R) is released
(d) energy is neither released nor absorbed

Correct Answer:

energy = 3VT (1/r-1/R) is released
