Which of the following factors change the value of the elastic constant of any material?

The elastic constant of a material is determined by the ________________ of potential energy vs interatomic distance curve.

The variation of interatomic energy with atomic distance is given by the following equation V(r)=4 [( /r12) ( /r6)] Where V(r) is the potential energy, and r is interatomic distance. and are constant.Find the value of energy at the point where the interatomic force is zero?
