Two capillary tubes of different diameters are dipped in water. The rise of water is
- A the same in both tubes
- B greater in the tube of larger diameter
- C greater in the tube of smaller diameter
- D independent of the diameter of the tube
Answer & Solution
Correct Answer
(C) greater in the tube of smaller diameter
Step-by-step Solution
Detailed explanation
Height of water in capillary tube
\(h=\frac{2 T}{r d g}\)
\(\therefore h \propto \frac{1}{r}\)
where \(h\) is height of the liquid and \(r\) is radius of tube so we can say that the rise of water is greater in the tube of smaller diameter.
\(h=\frac{2 T}{r d g}\)
\(\therefore h \propto \frac{1}{r}\)
where \(h\) is height of the liquid and \(r\) is radius of tube so we can say that the rise of water is greater in the tube of smaller diameter.
