A capillary tube when immersed vertically into a liquid records a rise of 3 cm . If the tube is held immersed in the liquid at an angle of `30^(@)` with the vertical , the liquid column along the tube will be

`3 . 464` cm

3 cm

`4.5 ` cm

`7.5` cm

Text Solution

Verified by Experts

The correct Answer is:

`h = l cos theta` ,
` :. l = h/(costheta) = 3/(cos30^(@))= (3xx2)/(sqrt(2))=3.464` cm
