Water rises up to a height h in a certain capillary tube of a particular diameter. Another capillary tube is taken whose diameter is half that of the previous tube. The height up to which water will rise in the second tube is

A

`3h`

B

`2h`

C

`4h`

D

`h`

Text Solution

Verified by Experts

The correct Answer is:
B
As `h prop 1/r, so (h)/(h.)=(r.)/(r)`
Here, `r.=(r)/(2) or, r=2r.`
`therefore (h)/(h.)=(r.)/(2r.) or, h.=2h`
