Answer: strong nuclear forces and electrostatic forces of repulsion
Explanation:
Strong nuclear force are acting within a nucleus.
Hence, Option (A) is correct answer.
The force that acts between the neutron of atoms and proton of atoms is called Nuclear force.
The strong forces are forces in which nucleus are not observed outside the nuclei.
Electrostatic force is also called as Coulomb force or Coulomb interaction which is an attractive force between the particles are caused because of their electric charges.
Thus from the above conclusion we can say that Strong nuclear force are acting within a nucleus.
Hence, Option (A) is correct answer.
