    Angular momentum of an electron in the nth orbit of hydrogen atom is given by :

    A)  \[\frac{nh}{2\pi }\]                                        

    B)  \[nh\]

    C)  \[\frac{2\pi }{nh}\]                                        

    D)  \[\frac{\pi }{2nh}\]

    Correct Answer: A

    Solution :

    According to Bohr, an electron can move only in those orbits in which its angular momentum is a simple multiple of \[\frac{h}{2\pi }\] i.e., equal to \[\frac{nh}{2\pi }\] (where n, is an integer)
