Respuesta :

At d, it is Q/d^2, and at 2d it is Q/(2d)^2 = Q/(4d^2). It is Coulomb's law

Answer:

E / 4

Explanation:

The formula for the electric field is given by

E = k Q / d^2

It shows that the electric field is inversely proportional to the square of distance.

So, if the distance is doubled, the electric field becomes one fourth.

It means the electric field is E / 4
