An electric field is a region in space where a force is exerted on a positive test charge. It is a region that would cause a test charge to move if it were placed within the region.
Electric Lines of Force- lines that represent the direction that a freely moving positive test charge will move in an electric field. These lines originate at positively charged objects and terminate at negatively charged objects.
The strength of on electric field is shown by the distance between field lines. The filed is stronger when the lines are closer together.
The field lines want to be as far part as possible from each other. When the charge is negative the field lines will point towards it and positive they will point away format he charge.
1st ~ B < A
2nd~ C < D
3rd~ G < E < F
4th~ J < H < I
We determine this by the number of field lines coming off or going to the charges.
