    In the figure below is shown the flow of the liquid through a horizontal pipe. Three tubes A, B and C are connected to the pipe. The radii of the tubes A, B and C at the junction are respectively 2 cm, 1 cm and 2 cms. It can be said that

    A)  the height of the liquid in the tube A is maximum

    B)  height of the liquid in the tube A and tube B is the same

    C)  height of the liquid in all the three tubes is the same

    D)  height of the liquid in tube A and C is the same  

    Correct Answer: D

    Solution :

     The rise of water in capillary tube is inversely proportional to radius. \[h=\frac{2T}{r\rho g}\]. It is given that radius of A and C are same. So, height of the liquid in tube A and C is the same.
