Question

electric force between two charged spheres is 18 units. if the distance between the centers of the sphere is tripled the electric field will be ???

Answer 1

Hi thank you for asking the question

I have a answer for you

Forces vary inversely as the as the distance between them changes

So :

18 / f.  = 1 / d ^ 2 / 1 /  ( 3 d ) ^ 2  = 9.

If the force between the charges is f  when distance is increased from d to 3d.

f =2 units

Hope this solution suffice your question
