Water rises upto a height h in a capillary tube of a certain diameter. This capillary tube is replaced by a similar tube of half the diameter. Now, calculate the height of water will rise.

Text Solution

Verified by Experts

`h = (26 costheta)/(rPg) h prop r prop R^-1`
Where D id diameter the capillary tube and
`h^.= 2/D`.
`therefore (h^.)/h = 2 or h^1` =2h
