A water drop of diameter cm is broken into 64 equal droplets. The surface tension of water is 0.075 N/m. In this process the gain in surface energy will be:
Text Solution
Verified by ExpertsThe correct answer is:
A
d= 2cm; r = 1 cm; T = 0.075
SE = T 
A
= 0.075(A f -A 1 )
A i =4 
r 2
A f = 
x 64
By volume conservation
