Which statement best describes electric forces?

• A. They require direct contact to act.
• B. They can act at a distance without direct contact.
• C. They only exist between magnets.
• D. They only operate in a vacuum.

Answer: (B)

Electric forces come from electric charges and act through the electric field, so they can influence another charge without touching. They can attract or repel depending on the signs of the charges. The strength depends on how much charge there is and how far apart they are, and it follows Coulomb’s law: the force grows with the product of the charges and shrinks with the square of the distance. Thinking in terms of fields helps: a charged object creates an electric field, and a second charge in that field experiences a force along the line connecting the two charges. These forces can operate in air, water, or a vacuum—they don’t require contact. So the key idea is that electric forces can act at a distance without direct contact.
