Answer:
A. Electric force acts at a distance.
Step-by-step explanation:
"Electric force," just like gravitational force is a "non-contact force." This means that even at a distance, two objects with no physical contact will create movement with the help of electric force. This leads to the concept of "force fields or field force" that explains why a charge object alters the region surrounding it. Once an object enters the region, it immediately experiences its force. An example of this is holding out one's hand near a "Van de Graaff generator." The electric force compels the hair strands to stand up.
