Please correct answer and don't used hand raiting

Consider the following Figure 2 and two atoms that are initially an infinite distance apart, x =00, at which point the potential energy of the system is U = 0. If they are brought together to x = x, the potential energy is related to the total force P by dU dx = P Given this, qualitatively sketch the variation of U with x. What happens at x=x? What is the significance of x = x, in terms of the potential energy? 0 P, Force 19 Attraction Total Repulsion x, Distance Figure 2. Variation with distance of the attractive, repulsive, and total forces between atoms. The slope dP/dx at the equilibrium spacing xe is proportional to the elastic modulus E; the stress σb, corresponding to the peak in total force, is the theoretical cohesive strength.
