1.) Law of Induction.
2.) Increase Winding Count
Answer:
Distance between both the object will be 404.51 m
Explanation:
We have given charge on two objects 
Coulomb force between the two objects is given F = 5.5 N
We have to fond the distance between both the object so that force between them is 5.5 N
According to coulomb law force between two charge particle is 
So 

r = 404.51 m
So distance between both object will be 404.51 m
Is there supposed to be options with this or are those the options there, steeper and smaller
