Strong and gravitational are the two fundamental forces that are attractive only
This is further explained below.
Generally, The strong interaction restricts quarks into protons, neutrons, and other hadrons. Strong contact bonds neutrons and protons to form atomic nuclei, termed the nuclear force.
Atoms' protons and neutrons are what make up the nuclear force, which is a force that operates between them. The protons and neutrons that are contained inside a nucleus are held together by a force known as the nuclear force. This force may occur between neutrons and protons, protons and neutrons, or neutrons and neutrons. It can also exist between protons and neutrons. This force is what maintains the structure of the nucleus of the atom,
In conclusion, The two basic forces that solely exert an attractive pull are the strong and gravitational forces. All entities that have mass or energy are mutually attracted to one another due to the basic interaction known as gravity.
