Which type of force is an attractive force acting between any two objects?

The gravitational force is indeed the attractive force that acts between any two objects with mass. This fundamental force is responsible for the attraction between objects, which becomes particularly evident on a large scale, such as between planets and stars, as they exert a gravitational pull on each other.

The strength of the gravitational force between two objects depends on their masses and the distance between them, as described by Newton's law of universal gravitation. This force acts over infinite distances, although it diminishes with an increase in distance. It is a key force that shapes the structure of the universe, governing the motion of celestial bodies and keeping them in orbit.

In contrast, the electromagnetic force acts between charged particles and can be both attractive and repulsive, depending on the charges involved. The nuclear force operates at a very short range, binding protons and neutrons within an atomic nucleus, and is not applicable to objects outside of atomic interactions. Centripetal force, on the other hand, is not a fundamental force but rather a resultant force that keeps an object moving in a circular path, directed towards the center of the circle.

Thus, the gravitational force is unique as it consistently attracts any two masses, making it the correct answer to the question.
