Why aren't positive and negative charges attracted to each other?

A stable dipole exists due to the presence of equal and opposite charges separated by a certain distance. These charges create an electric field that acts as a force to keep the dipole stable. Additionally, the dipole moment (a measure of the strength of the dipole) must be greater than or equal to zero for the dipole to be stable.
Symmetry plays a crucial role in the stability of a dipole. In a stable dipole, the charges must be equally and oppositely distributed on either side of the center of mass. This symmetry ensures that the dipole experiences no net force and remains stable.
Yes, a dipole can be stable without an external force acting on it. This is because the charges and the distance between them create their own electric field, which acts as a force to keep the dipole stable. However, an external force may affect the stability of the dipole.
The distance between the charges is a crucial factor in the stability of a dipole. As the distance between the charges increases, the dipole moment decreases, leading to a decrease in stability. On the other hand, decreasing the distance between the charges increases the dipole moment and therefore increases the stability of the dipole.
A stable dipole can become unstable due to external forces, changes in the distribution of charges, or changes in the distance between the charges. Additionally, if the dipole moment becomes significantly greater than zero, the dipole can become unstable. Similarly, if the dipole moment becomes too small, the dipole may also become unstable.
