    In a hydrogen atom following the Bohr's postulates the product of linear momentum and angular momentum is proportional to \[{{(n)}^{x}}\] where 'n' is the orbit number. Then 'x' is-

    A)  0 

    B)  2     

    C)  -2 

    D)  1

    Correct Answer: A

    Solution :

    [a] Linear momentum \[\Rightarrow mv\propto 1/n\] angular momentum \[\Rightarrow mv\propto n\] \[\therefore \]product of linear momentum and angular momentum cm0.
