    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                                                   [MP PET 2005]

    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 :

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