Electric Field Basics

Electric field is defined as the electric force per unit charge. 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.

Hence, we can say, if a charge is a positive charge, then the lines of force come out of this charge. But for a negative charge, these lines of force come into this charge.
