When a capillary is dipped in water, water rises 0.015 m in it. If the surface tension of water is `75 xx 10^(-3) N//m` , the radius of capillary is

A

0.1mm

B

0.5 mm

C

1mm

D

2 mm

Text Solution

Verified by Experts

The correct Answer is:
C
`h=(2sigma)/(rgrho)implies r=(2sigma)/(grhoh)=(2xx75 xx10^(-3))/(15xx10^(-3)xx10^3 xx10)=1mm`
