The fields from isolated, individual charges look like this:
When there is more than one charge in a region, the electric field lines will not be straight lines; they will curve in response to the different charges. In every case, though, the field is highest where the field lines are close together, and decreases as the lines get further apart. (Google)

The isolated positive charge is confined to it's location - exhibiting negative inertia (a tendency to remain at rest; resisting outside forces) - by the recoil of omnidirectionally expanding electrical energy. The isolated negative charge is confined to its location - also exhibting negative inertia (a resistance to outside forces) by the omnidirectional influx of electrical energy. - RP ______________________________ "The significance of personalities like Mach lies by no means only in the fact that they satisfy the philosophical needs of their times, an endeavor which the hard-nosed specialist may dismiss as a luxury. Concepts that have proven useful in ordering things can easily attain an authority over us such that we forget their wordly origin and take them as immutably given. They are then rather rubber-stamped as a "sine-qua-non of thinking" and an "a priori given", etc. Such errors make the road of scientific progress often impassable for long times. Therefore, it is not at all idle play when we are trained to analyze the entrenched concepts, and point out the circumstances that promoted their justification and usefulness and how they evolved from the experience at hand. This breaks their all too powerful authority. They are removed when they cannot properly legitimize themselves; they are corrected when their association with given things was too sloppy; they are replaced by others when a new system can be established that, for various reasons, we prefer." (Einstein, "Ernst Mach", Physikalishe Zeitschrift 17 (1916), 102; Collected Papers vol. 6, Doc. 29)The core of "Mach's Principle" is something like this: the inertia of a body is determined in relation to all other bodies in the universe (in short, "matter there governs inertia here"). But "inertia" here is ambiguous: inertial mass, or the property expressed by the law of inertia?
Mach states such ideas in the following parts, after he presented his famous objections against Newton's argument for absolute space. If, in a material spatial system, there are masses with different velocities, which can enter into mutual relations with one another, these masses present to us forces. We can only decide how great these forces are when we know the velocities to which those masses are to be brought. Resting masses too are forces if all the masses do not rest. ... All masses and all velocities, and consequently all forces, are relative. There is no decision about relative and absolute which we can possibly meet, to which we are forced, or from which we can obtain any intellectual or other advantage. (Mach, The Science of Mechanics, ch.2, vi-3, Open Court, 1960, 279)
Here, Mach talks about inertial mass, but his emphasis is on the relativity of motion. In order to understand Mach's assertion, you have to remember that Mach tries to define the notion of mass in terms of acceleration and the principle (law) of reaction.
