which best compares the gravitational force and the strong force?\nboth are attractive and repulsive.\nboth…

Answer:

Both are attractive only.

Brief Explanations:

The gravitational force is always attractive. The strong - force, which binds quarks together in protons and neutrons and holds the nucleus together, is also attractive. The electromagnetic force can be both attractive and repulsive. The strong force is much stronger than the electromagnetic force at short distances within the nucleus, while the gravitational force is much weaker than the electromagnetic force in most common situations.
