A capillary tube whose inside radius is ...

A capillary tube whose inside radius is 0.5 mm is dipped in water having surface tension `7.0xx10^(-2) Nm^(-1)`. To what height is the water raised above the normal water level ? Angle of contact of water with glass is `0^(@)`. Density of water is `10^(3) kg m^(-3)` and `g=9.8 ms^(-2)`.

Text Solution

Verified by Experts

The correct Answer is:
`2.356 xx 10^(-4)N`
`h = 2 rho cos theta // r rho g =0.0306m`, weight `= pi r^(2) h rho g = 3.14 xx ( 0.5 xx 10^(-3))^(2) xx 0.0306 xx 10^(3) xx 9.8 = 2.34 xx 10^(-4)N`.
