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Correct Answer: compression side of edge dislocation will attract and will be repealed to the tension side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.
