If in a crystal there exist a point defect of the interstitial atom and if solute atom smaller than the solvent atom, then which is true for the edge dislocation?

If in a crystal there exist a point defect of the interstitial atom and if solute atom smaller than the solvent atom, then which is true for the edge dislocation? Correct Answer compression side of edge dislocation will attract and will be repealed to the tension side

If the solute atom is smaller than the solvent, it will create a local region of tension. So the tension side of dislocation will repeal at this region, and compression side will attract from this region.
