A capillary tube of radius 0.20 mm is dipped vertically in water. Find the height of the water column raised in the tube. Surface tension of water `=0.075Nm^-1` and density of water `=1000 kgm^-3. Take g=10 ms^-2`.

Text Solution

Verified by Experts

We have
`h=(2Scostheta)/(rrhog)`
`=(2xx0.075Nm^-1xx1)/((0.20xx10^-3m)xx(1000kgm^-3)(10ms^-2))`
`=0.075m=7.5cm`
