    When a capillary of radius R is dipped into water, water rises upto height H and the mass of this liquid is M. Now if capillary of radius 2R is dipped into water. What will be the mass of the water rises in capillary:

    A)  M                          

    B)         2M                       

    C) \[\frac{M}{2}\]                                 

    D)         4M

    Correct Answer: A
