Any object that is electrically charged, it would emit an electric force lines, in all directions as shown in Figure 1.9.
Figure 1.9 The lines of electric force
At positively charged objects, then the electric force lines will radiate out objects, while the objects are negatively charged, the electric force lines heading into. The electric field is the area around the electrically charged objects are still influenced by the electric force. The electric field is described by the electric force lines.
The properties of the electric force lines
Electric lines of force coming from the positive charge toward the negative charge. Electric force lines never intersect. The closer the electric lines of force, the stronger the electric field. Figure 1.10 shows the interaction of the electric lines of force that occurred in the two charged objects. This phenomenon of course you will be able to clarify the nature of the phenomenon of electric charge.
