Answer:
The three best answers are:
Electric fields can be positive or negative (depending on source)
Electric fields can attrace or repel objets (assuming the object is charged)
Electric forces are strongest near the charged object E ∝ 1 / R^2
Knowing the direction of a force is important because it helps someone know the motion of the object. if you use a free body diagram, then it becomes easy to see all the forces being applied to an object. if there is more force going one way, the object is accelerating in that direction. if all the forces cancel each other out, then the object is at a constant speed or is at rest.
