Two uncharged, conducting spheres are separated by a distance d. When charge −Q is moved from sphere A to sphere B, the Coulomb force between them has magnitude F0. Is the Coulomb force attractive or repulsive? If an additional charge −Q is moved from A to B, and the distance between the centres of the spheres is doubled, what is the ratio of the new Coulomb force to the original Coulomb force?

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
