The dependence of tho potential energy `W` of the interaction between objects on the distance r separating thorn is shown ill t.he figure. What will be the distances between the objects that correspond `1.0` equilibrium positions? At what dislancc will the equilibrium be stable? (Answer the same question for unstable equilibrium.) What segments of the curve correspond to a repulsive force and what segments, to an attractive force?
