Quiz 3 DL Sec Name I certify by my signature that I will abide by the code grade (for office use only) of academic conduct of the University of California. Signature The plot above is a graph of the potential energy between two strange atoms. The horizontal axis, denoted by x, denotes the separation between the atoms. The vertical axis shows the potential energy. Based only on the graph above, answer the following questions (Please include a clear explanation of your answer for each part): (i) Classify the points A, B, C, D and E according to the nature of the force between the atoms at these points i.e. whether the force is attractive, repulsive or zero. (ii) We know that the usual Lennard Jones potential repels infinitely strongly if two atoms try to overlap exactly (i.e. the separation goes to zero). Explain if the same holds true for the potential depicted above.

Unformatted text preview: (iii) Suppose the well-depth at point C is denoted by . Two atoms had a net kinetic energy of +1.5 at point C. What is the minimum amount of work you need to do on the two atoms to separate them to infinity? (Given that the value of the potential at D is +0.6 ). (iv) At point E, what is the net kinetic energy of the two atoms from part (iii)? (v) Suppose the plot of the potential continues as depicted above for very large values of x i.e. the potential continues to decrease linearly with x as x ! What is the nature of the force between the atoms when they are very far apart?
