The work done to split a liquid drop id radius `R` into `N` identical drops is (taken `sigma` as the surface tension of the liquid)

The ratio of work done in blowing a liquid drop to radius R and to radius 3R is

The ratio of work done in blowing a liquid drop to radius R and to radius 3R is

The work done in breaking a spherical drop of a liquid of radius R into 8 equal drops is

A certain number of spherical drops 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

A spherical liquid drop of radius R is split up ino 8 equal droplets .If T is the surface tension of the liquid , then the work done in this process is
