Characteristics of nuclear ball 1. Nuclear balls are just attractive balls. The intensity of this ball is much higher than that of gravitational and electromagnetic balls. 2. This ball is charge neutral. Nuclear ball values remain the same for positively charged protons and uncharged neutrons, meaning that there is no difference between proton-proton , neutron-neutron or proton-neutron balls at the same distance. 3. This is a short range ball. Its range is 10-14m, which means that the nuclear force is very strong at a distance of 10-14m between the nucleus and it has no effect on the outside of the ball. Thus nucleons are bound only to their adjacent nuclei and not to distant nucleons.
