If a capillary tube of diameter 0.4 m is dipped vertically into water, then the height to which water rises in the capillary tube will be ,

`7.143` cm

`0 . 013` cm

`714 .3` cm

7143 cm s

Text Solution

Verified by Experts

The correct Answer is:

` h = (2T cos theta )/(rho gr) = (2xx 7xx 10^(-2)xx1)/(10^(3)xx9.8 xx2xx10^(-4))=7.143` cm
