    The points of maximum and minimum attraction in the curve between potential energy (U) and distance (r)of a diatomic molecules are respectively

    A) Sand R

    B)             T and S

    C)             R and S

    D)             S and T

    Correct Answer: D

    Solution :

                    Attraction will be minimum when the distance between the molecule is maximum. Attraction will be maximum at that point where the positive slope is maximum because  \[F=-\frac{dU}{dx}\]
