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

Answer:

Solution:

$h = \frac{2 T c o s θ}{r _{ρ} g} ∴ hr = \frac{2 T c o s θ}{ρ g} =$ constant $∴ h_{1} r_{1} = h_{2} r_{2} \Rightarrow h_{2} = \frac{h _{1} r _{1}}{r _{2}} ∴ (\frac{r _{2}}{r _{1}} = \frac{1}{3})$ Substituting the values $h_{2} = (2.0) (3) = 6.0 cm$ \end{document}
