    In any Bohr orbit of the hydrogen atom, the ratio of kinetic energy to potential energy of the electron is [MP PET 1994]

    A)            1/2

    B)            2

    C)            \[-1/2\]                                  

    D)             ? 2

    Correct Answer: C

    Solution :

               \[K.E=\frac{kZ{{e}^{2}}}{2r}\] and \[P.E.=-\frac{kZ{{e}^{2}}}{r};\] \ \[\frac{K.E.}{P.E.}=-\frac{1}{2}\].
