Scientists represent electric field strength is a vector quantity, rather than as a scalar quantity. From this, we can infer that an electric field has magnitude and direction. What accounts for the directional nature of the electric field?
A)
law of attraction: opposite charges attract, like charges repel

B)
Ohm's law: electrons moving through a conductor to create a circuit

C)
voltage: is the potential difference between one conductor and another
Eliminate

D)
gravity: any object, with mass, even a particle, has an attractive force
