Which of the following describes a noncontact force?

Explanation:
Noncontact forces act on objects without touching them. They operate at a distance, so the interaction doesn’t require contact between objects. Gravity pulls objects toward each other even when nothing is between them, and magnetic or electric forces can attract or repel without contact as well. In contrast, friction and the normal force happen only when surfaces are in contact, so they’re contact forces. Saying the force type is a noncontact force captures the idea of acting without direct touch, which is exactly what this choice describes.
