If million small drops of water coalesce into one larger drop, then the ratio of total surface energy of the larger drop to that of the smaller drops combined will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
be the radius of each droplet and 
be the radius of the big drop.
Since the total volume is the same, we have
The surface energy of one million drops,
The surface energy of one big drop,
