[math]E = \frac{1}{4\pi\epsilon_0}\frac{q}{r^2}\hat{r}[/math]This is a formula for an electric field of a sphere and the author makes a comment (Example 2.3 fundamentals of electrodynamics by Griffiths) "Notice a remarkable feature of this result: The field outside the sphere is exactly the same as it would have been if all the charge had been concentrated at the center." But how is that possible if in the formula above we clearly see that the electric field weakens as we move further from the sphere center proportionally to [imath]\frac{1}{r^2}[/imath](even intuitively it makes sense)
