Gravitational force shares a common feature with electromagnetic force. In both cases, the force is
Explanation
Gravitational and electromagnetic forces are two of the four fundamental forces of nature that share the unique characteristic of being long-range forces. Unlike the strong and weak nuclear forces, which are effective only over subatomic distances, both gravity and electromagnetism follow an inverse-square law, meaning their influence extends theoretically to an infinite distance [1]. While gravitational force acts between all objects with mass and is always attractive, the electromagnetic force acts specifically between charged particles and can be either attractive or repulsive [2]. Despite these differences in source and nature, their shared mathematical dependence on the square of the distance allows them to govern large-scale structures in the universe, such as the movement of galaxies and the behavior of light across intergalactic space.
