Water rises in a capillary tube of radius ' $r$ ' upto a height ' $h$ '. The mass of water in a capillary is ' $m$ '. The mass of water that will rise in a capillary tube of radius $\frac{’ r ’}{3}$ will be

Options:

Answer:

Solution:

$∴ ∴ ∴ ∴ h \propto \frac{1}{r} Mass of water in a capillary, m = π r^{2} h ρ m \propto r^{2} h m \propto r^{2} / r \frac{m _{2}}{m} = \frac{\frac{r}{3}}{r} m_{2} = \frac{m}{3}$
