    Water rises to a height h in a capillary at the surface of earth on the surface of the moon the height of water column in the same capillary will be

    A) \[6h\]                                   

    B) \[h/6\]

    C)  \[h\]                                    

    D)  \[zero\]

    Correct Answer: A

    Solution :

    Height\[h=\frac{2S\cos \theta }{r\rho g}\] As on surface of moon\[{{g}_{m}}=\frac{g}{6}\] Hence,  \[{{h}_{m}}=6\,\,h\]
