Answer:
as we move the two charges apart the attraction force between them will decrease in magnitude
Step-by-step explanation:
As we know that two charges are unlike charges here so the force between them is attraction type of force
This force is given by Coulomb's law which is given as

so here this force is proportional to the product of two charges and inversely depends on the square of the distance between two charges
So here keeping the same magnitude of the charges we move them to large distance
So here the force between them must have decrease
So as we move the two charges apart the attraction force between them will decrease in magnitude
