Change Of State

Step 1: Concept
At the moment the drop breaks away, the upward force due to surface tension balances the downward weight of the drop.
Step 2: Analysis
Surface tension force ( ) = . Weight of the drop ( ) = .
Step 3: Calculation
Equating forces: . Solving for : .
Step 4: Conclusion
Hence, the surface tension is .
Final Answer:(B)

The correct option is (C) : Deposition
