The electric field at a point P is defined as the force per unit charge experienced by a small positive test charge q0 placed at the point P. Both q0 and the corresponding point P are illustrated in the animation. For the case where the electric field is that due to a point charge q, we may use Coulomb's law to find the magnitude of the electric field. The direction of is determined by the direction of the force on q0, as indicated in the animation. Match each item on the left with the most appropriate item on the right. A) The electric field vector E points radially out. B) The magnitude of vector E gets smaller for smaller separations. C) The magnitude of vector E gets smaller for larger separations. D) The electric field vector E points radially in.
