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 \(\theta_1\), \(\theta_2\), and \(\theta_3\) 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.
