Vedclass · Answer

(C) The charge density inside a nucleus is approximately constant up to a certain radius,known as the nuclear radius $R$. Beyond this radius,the density falls off rapidly to zero. This behavior is characteristic of the distribution of nucleons within the nucleus. Looking at the provided graphs,graph $C$ shows a constant value for $P$ near the center $(r=0)$ and a sharp decrease as $r$ approaches the nuclear surface. Therefore,graph $C$ is the correct representation.

The charge density $P$ in a nucleus varies with distance $r$ from the centre of the nucleus according to the curve in the figure. Which of the following graphs correctly represents this variation?
