A capillary tube of radius $$r$$ is immersed in water and water rises in it to a height $$h.$$ The mass of the water in the capillary is $$5$$ g. Another capillary tube of radius $$2r$$ is immersed in water. The mass of water that will rise in this tube is:

 1 $$5.0$$ g 2 $$10.0$$ g 3 $$20.0$$ g 4 $$2.5$$ g

Three liquids of densities $$\rho_1,\rho_2$$ and $$\rho_3$$ $$(\rho_1>\rho_2>\rho_3)$$ having the same value of surface tension $$T$$, rise to the same height in three identical capillaries. The angles of contact $\mathrm{}$$$\theta_1$$, $\mathrm{}$$$\theta_2$$, and $\mathrm{}$$$\theta_3$$ obey:
1. $$\frac{\pi}{2}>\theta_1>\theta_2>\theta_3 \geq 0$$
2. $$0 \leq \theta_1<\theta_2<\theta_3<\frac{\pi}{2}$$
3. $$\frac{\pi}{2}<\theta_1<\theta_2<\theta_3<\pi$$
4. $$\pi>\theta_1>\theta_2>\theta_3>\frac{\pi}{2}$$

Water rises to height '$$h$$' in a capillary tube. If the length of capillary tube above the surface of the water is made less than $$'h'$$, then:

 1 water does not rise at all. 2 water rises up to the tip of capillary tube and then starts overflowing like a fountain. 3 water rises up to the top of capillary tube and stays there without overflowing. 4 water rises up to a point a little below the top and stays there.
