Water rises in a capillary tube to a height of 2.0 cm. In another capillary tube whose radiuus is one third of it, how much the water will rise?

A

3 cm

B

5 cm

C

9 cm

D

6 cm

Text Solution

Verified by Experts

The correct Answer is:
D
`h=(2xcostheta)/(rrhog)`
`hr=(2scostheta)/(rhog)="constant"`
(or) `h_(1)r_(1)=h_(2)r_(2)orh_(2)=(h_(1)r_(1))/(r_2)`
Substituting the values `h_(2)=(2.0)(3)=6.0cm`
