Electric Field. Around every electrically charged object is a force field that can be detected and measured. This force field can cause electric charges to move in the field Electric field is defined as the electric force per unit charge. E = F/Q The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge. Electric field lines can be drawn using field lines. They are also called force lines. (Positive charge electric field) The field lines are origina ted from the positiv e charge. (Negative charge electric field) The field lines end up at the negativ e charge.

Electric Field.
Around every electrically charged object is a force field that can be detected and
measured. This force field can cause electric charges to move in the field
Electric field is defined as the electric force per unit charge.
E = F/Q
The direction of the field is taken to be the direction of the force it would exert on
a positive test charge.
The electric field is radially outward from a positive charge and radially in toward
a negative point charge.
Electric field lines can be drawn using field lines. They are also called force lines.
(Positive charge electric field)
The field lines are originated from the positive charge.
(Negative charge electric field)
The field lines end up at the negative charge.
A positive charge exerts out and a negative charge exerts in equally to all directions; it is symetric. Field lines are drawn to show the direction and strength of field. The closer the lines are, the stronger the force acts on an object. If the lines are further each other, the strength of force acting on a object is weaker.
