An uncharged conducting sphere is brought in contact with an identical sphere having a charge of \(4 \times 10^{-8} \mathrm{C}\). After contact, the spheres are separated and placed at a distance such that the electrostatic force between them is \(9 \times 10^{-3} \mathrm{~N}\). Find the distance between the spheres.
