Pure water rises in a capillary tube upto a height of 8 cm . If surface tension of water and acceleration due to gravity are 80 dyne/cm and 1000 `cm//s^(2)` respectively , then the radius of capillary tube will be

A

2 cm

B

`0.2` cm

C

20 cm

D

` 0.02 ` cm

Text Solution

Verified by Experts

The correct Answer is:
D
` r = (2T cos theta )/(h rho g) = (2xx80xx1)/(8xx1xx1000)=0.02` cm
