  • question_answer
    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                            [MP PMT 2001]

    A) 6h

    B)                      \[\frac{1}{6}h\]

    C)             h         

    D)             Zero

    Correct Answer: A

    Solution :

                    \[h=\frac{2T\cos \theta }{rdg}\]\\[h\propto \frac{1}{g}\] As \[{{g}_{m}}=\frac{{{g}_{e}}}{6}\]\ \[{{h}_{m}}=6{{h}_{e}}\]
