A) liquid will form foundation
B) liquid will not rise
C) the meniscus will adjust itself so that the water does not spill
D) None of the above
Correct Answer: C
Solution :
If the length of the tube h' is less than h, it is found that the liquid does not overflow. In a tube of insufficient length, the liquid rises upto the top of the tube and increases the radius of curvature, of its meniscus to a value R', so that smaller the length (h') of the tube, greater will be the radius of curvature (R?) of the meniscus, and the liquid will never overflow.
