    Directions For Questions

    Answer the following by appropriately matching the lists based on the information given in the paragraph.
    Consider the Bohr's model of a one -electron atom where the electron moves around the nucleus. In the following $$List-I$$ contains some quantities for the $$n^{th}$$ orbit of the atom and $$List-II$$ contains options showing how they depend in $$n$$.

    List-I
    List-II
    (i)Radius of the $$n^{th}$$ orbit(P)$$\propto n^{-2}$$
    (ii)Angular momentum of the electron in the $$n^{th}$$ orbit(Q)$$\propto
    n^{-1}$$
