Electrostatic interaction between two conducting spheres

In the paper we consider the problem of the electrostatic interaction between two charged conducting spheres with arbitrary electrical charges and radiuses. Using the image charges method we determine exact analytical formulas for the force F and for the potential energy W of the interaction between these two spheres as well as for the potential V of the electromagnetic field in an arbitrary point created by them. Our formulas lead to Coulomb’s law for point charges.We theoretically prove the experimentally shown fact that two spheres with the same type (positive or negative) of charges can also attract each other.

► Electrostatic interaction between charged spheres with random charges and radiuses.
► The force of such interaction is determined.
► The potential energy and potential of such interaction are determined.
► It is proven that two spheres with the same kind of charges can attract each other.
