A) \[\sqrt{\frac{T}{\rho }\left( \frac{1}{r}-\frac{1}{R} \right)}\]
B) \[\sqrt{\frac{2T}{\rho }\left( \frac{1}{r}-\frac{1}{R} \right)}\]
C) \[\sqrt{\frac{4T}{\rho }\left( \frac{1}{r}-\frac{1}{R} \right)}\]
D) \[\sqrt{\frac{6T}{\rho }\left( \frac{1}{r}-\frac{1}{R} \right)}\]
Correct Answer: D
Solution :
[d] When drops combine to form a single drop of radius R. |
Then energy released, |
If this energy is converted into kinetic energy then |
