Electric Fields lines and Forces

Electric Fields:-

"Electric Fields are the area or space or region around a body or particle which is charged, in which area it effects(attracts or repel) on other body or particle which is charged."

Explanation:-

Consider their is a charged particle A, it has Electric fields lines, because it is charged. When a unit positive charge(small charge) will come into its field lines then it will feel some force, which is the effect of Charged particle A. It will repel the unit charge (as positive and positive repel each other).

The unit positive charge will only feel this force when it will come into the region where there is Electric field lines of Particle A.

In above diagram unit charge 1 will feel force as it is in the field region of charged particle A, but 2 will not feel any force as it is out of field lines of charged particle A. 

Electric Forces:-

"The force which charged unit positive charge feel when it is in the electric field lines of charged particle (A)."

Explanation:-

As Charged particle have electric field region where it exerts some force on some other charged particle (when it comes in the electric field of that charge). There are two type of forces which is exert by the charged particle in its field region. Attractive force and Repulsive force. Positive charge exert repulsive force on other positive charged while it exert attractive force on negative charge. In general there is attractive forces in opposite charges and there is repulsive force in between like charges.  

In below pic A is positive charge and it is repelling other positive charge.

In below pic, A is positive charge which is attracting negative charge.
