If the surface tension of water is 0.06 Nm, then the capillary rise in a tube of diameter 1mm is `(theta=0^(@)`)

1.22 cm

2.44 cm

3.12 cm

3.86 cm

Text Solution

Verified by Experts

The correct Answer is:

`h=(2S costheta)/(r rhog)=(2xx0.06xxcos0^(@))/(0.5xx10^(-3)xx10^(3)xx9.8)`
`=2.44xx10^(-2)m=2.44 cm`
