MCQ
Water falls from a tap, down the streamline.
- ✓Area decreases
- BArea increases
- CVelocity same
- DArea remains same
✓
Answer
Correct option: A.
Area decreases
a
When water falls from a tap, down the streamline area decreases due to increase in velocity of liquid as it experiences gravity, i.e., by equation of continuity.
