    As the electron in Bohr orbit of Hydrogen atom passes from state \[n=2\] to \[n=1\], the kinetic energy K and potential energy U change as

    A) K two-fold, U four-fold

    B) K four-fold, U two-fold

    C) K four-fold, U also four-fold

    D) K two-fold, U also two-fold

    Correct Answer: C

    Solution :

    [c] \[U=2E,\] \[K=-E\] and \[E=-\frac{13.6}{{{n}^{2}}}=eV\].
