Vedclass · Answer

(A) For light nuclei,the number of protons $(Z)$ is approximately equal to the number of neutrons $(N)$,so the plot follows the $N=Z$ line (slope $45^{\circ}$).As the atomic number increases,the long-range electrostatic repulsion between protons increases faster than the short-range attractive nuclear force.To maintain stability in heavier nuclei,more neutrons are required to provide additional attractive nuclear force without adding electrostatic repulsion.This causes the curve to bend towards the $x$-axis (neutron axis),meaning $N > Z$ for stable heavy nuclei.Thus,$STATEMENT-1$ is True and $STATEMENT-2$ is True,and $STATEMENT-2$ is the correct explanation for $STATEMENT-1$.
