Question

How are protons, which are positively charged, held together inside a nucleus? Explain the variation of potential energy of a pair of nucleons as a function of their separation. State the significance of negative potential energy in this region?

Answer 1

The core of a particle is held together by the solid nuclear forces/ atomic power that ties together protons and neutrons. In spite of the fact that the solid atomic power is the most grounded of the four crucial powers, it acts just over short - commonly atomic - separations. It ties together the protons and neutrons in the core.  

1. Nuclear forces are more grounded and attractive than electrostatic powers.  
2. These powers are charge autonomous.

The figure is given below that shows the potential energy of pair of nucleons.  The negative potential vitality shows the power of fascination b/w the pair of nucleon.
