A capillary of radius r is immersed in water and water rises in it to height h. The mass of the water in the capillary is 5 g. Another capillary tube of radius 2r us immersed in water. The mass of water that will rise in this tube is:
Option: 1  2,5 g
Option: 2 5.0 g
Option: 3  10. g  
Option: 4 20.0 g

Mass of water in the capillary tube = m=\rho Ah

and using

h=\frac{2T\cos \Theta }{\rho gr}

we get

m=\rho Ah=\rho *(\pi r^2)*\frac{2T\cos \Theta }{\rho gr}\\ \Rightarrow m \ \alpha \ r

So \frac{m_2}{m_1}=\frac{r_2}{r_1}=\frac{2r}{r}=2\\\\ m_2=2\times m_1=2\times 5=10 \ g
