Water rises upto height h in a capillary...

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

A

4h

B

3h

C

2h

D

`(1)/(2)h`

Text Solution

Verified by Experts

The correct Answer is:
D
According to Jurin's law, rise in capillary is inversely proportional to the radius of capillary.
or `h prop (1)/(r ) or (h_(2))/(h_(1))=(r_(1))/(r_(2))=(d_(1))/(d_(2))`
Given `d_(2)=2d_(1)`
`therefore (h_(2))/(h_(1))=(d_(1))/(2d_(1))=(1)/(2)`
`or h_(2)=(h_(1))/(2)=(h)/(2)`
