The figure shows the potential energy of two interacting atoms. The distance withthe minimum potential energy is r0 and the distance where the curve crosses 0 is r1.What does this curve say about the force between the two atoms? Choose all thecorrect answers.10 The magnitude of the force between the two atoms is largestat separation r0.| The magnitude of the force between the two atoms is zero atseparation r0.The force is repulsive only for separations less than r0.( The force is repulsive only for separations less than r1.The force gets weak at large separations.The force gets weak at small separations.V None of the above.

Given is the potential energy of two atoms as a function of separation between them. This is used for explanation of formation of molecule. KEYPOINT: Force is given by negative of gradient of potential energy. EXPLANATION: Initially, there is an attractive force between two atoms as they start approaching each other. This is indicated by negative potential energy. The energy goes on decreasing till it reaches point r0 where potential energy is minimum. This is point of maximum stability. Here, attractive and repulsive forces balance each other. If atoms approach closer than r0, potential energy starts increasing. At distance r1, potential energy becomes zero, hence no force keeps atoms together. For distances closer than r1 ,system becomes unstable as repulsive force begins to dominate. Potential energy goes on increasing for such close distances.Based on above explanation, correct answers are as below: The force is repulsive only for separations less than r1. The force gets weak at small separations. The force gets weak at large separations.
