A capillary tube is dipped vertically in a liquid. If the liquid surface is hemispherical, then the angle of contact \(\theta\) is :-
1 \(\theta=90^{\circ}\)
2 \(\theta=0^{\circ}\)
3 \(\theta>0^{\circ}\)
4 \(0 < \theta>90^{\circ}\)
Explanation:
If angle of contact is 0 , then meniscus shape is hemispherical.

A capillary tube of radius \(R\) is immersed in water and water rises in it to a height \(H\). Mass of water in the capillary tube is \(M\). If the radius of the tube is doubled, mass of water that will rise in the capillary tube will now be
1 \(2\,M\)
2 \(M\)
3 \(M/2\)
4 \(4\,M\)
Explanation:
Mass of liquid in capillary tube \(M=\pi R^{2} h \times \rho=\pi R^{2} \rho \dfrac{2 T \cos \theta}{\rho R g}\) \(\therefore \quad M \propto R\). If radius becomes double, then mass will become twice.
