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
Correct Answer: C
Solution :
Height of water in capillary tube \[h=\frac{2T}{r\,dg}\] \[\therefore \] \[h\propto \frac{1}{r}\] 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.
