where ke is the Coulomb's constant while d is the distance between the two charges.
We can see that the force F scales as the inverse of the square of the distance: . Therefore, when the two objects move apart from each other, the distance increases and therefore the force between them decreases.
as we move the two charges apart the attraction force between them will decrease in magnitude
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
