The decision of a problem on force of interaction of a point charge with a dielectric ball which is represented in the form of the infinite sum is resulted. It is shown that in a case when dielectric permeability of a ball aspires in infinity, force of interaction aspires to force of interaction of a point charge with the conducting isolated ball which contains only one composed. n the basis of the received results the simple approached formula for calculation of force of interaction of a point charge and the dielectric ball, containing too only one composed is offered. Using the received formula, the problem about force of interaction of a point charge and the same charged dielectric ball is solved. For various values of parameters the neutral curves dividing scopes of forces of pushing away and an attraction are constructed.
