    The potential energy U of two atoms of a diatomic molecule as a function of distance r between the atoms is shown in the given figure.                 Read the following statements carefully                 The equilibrium separation distance between the atoms is equal to \[{{r}_{2}}\]                 At \[\text{r}={{\text{r}}_{\text{1}}},\]the force between the atoms is repulsive                 For \[\begin{align}   & \text{V}{{\text{p}}^{\text{2}}}= \\  &  \\ \end{align}\] the force between the atoms is attractive TO.                 Which of the above statements is true?

    A)  1 only                                  

    B)  2 only

    C)  3 only                                  

    D)  2 and 3

    Correct Answer: A

    Solution :

                     Its the distance decreases attraction increase. So the equilibrium separation distance between the atoms is equal to\[{{r}_{2}}\].
