Two capillary tubes of radii 0.2 cm and ...

Two capillary tubes of radii 0.2 cm and 0.4 cm are dipped in the same liquid.The ratio of heights through which liquid will rise in the tube is

A

`1:2`

B

`2:1`

C

`1:4`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:
B
capillary use
`h=(2Tcos(theta))/(r rhog)`
`therefore=(h_(1))/(h_(2))=(r_(2))/(r_(1))=(0.4)/(0.2)=2:1`
