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.

(a)Is the Coulomb force attractive or repulsive?

attractive repulsive

(b) If an additional charge −Q is moved from A to B, what is the ratio of the new Coulomb force to the original Coulomb force,(c) If sphere B is neutralized so it has no net charge, what is the ratio of the new to the original Coulomb force,

No the weight would be changed due to the different gravity. The density won't change though. This is due to the density is related to the hydrogen bond between water
