A spherical liquid drop of radius R is divided into 8 equal droplets. If the surface tension is T, then work done in the process will be:
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
be radius of each small droplets.
Since the volume remains the same
Surface area of big droplet 
Surface area of 8 small droplets 
Increase in surface area 
Work done 
Surface tension x increase in surface area
