In a capillary tube, water rises to 3 mm . The height of water that will rise in another capillary tube having one-third radius of the first is

A

1 mm

B

3 mm

C

6 mm

D

9 mm

Text Solution

Verified by Experts

The correct Answer is:
D
hr = constant.
`implies h_1/h_2 =r_2/r_1implies3/h_2 =(r//3)/r implies h_2 =9` mm
