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

A

4h

B

3h

C

2h

D

`h/2`

Text Solution

Verified by Experts

The correct Answer is:
C
From capillary tube experiement we know that
`h=(2s cos theta)/(r rho g)` i.e. `h prop1/r`
`:.(h.)/h=r/(r//2)=2 or h.=2h`
