Which of the following is true for a sample of $U^{235}$ and $U^{238}$ isotopes?

If the radius of a nucleus with atomic number $Z = 50$ is $9 \times 10^{-15} \ m$,what is the electric potential at its surface?

What is the nucleus of an atom?

$STATEMENT-1$: The plot of atomic number ($y$-axis) versus number of neutrons ($x$-axis) for stable nuclei shows a curvature towards the $x$-axis from the line of $45^{\circ}$ slope as the atomic number is increased.
$STATEMENT-2$: Proton-proton electrostatic repulsions begin to overcome attractive nuclear forces in heavier nuclides,requiring more neutrons to maintain stability.
