Question

Given below are two statements: one is labelled as Assertion **A** and the other is labelled as Reason **R**.

Assertion **A**: The nuclear density of nuclides $$^{10}_{5}B$$, $$^{6}_{3}Li$$, $$^{56}_{26}Fe$$, $$^{20}_{10}Ne$$ and $$^{209}_{83}Bi$$ can be arranged as $$N_{Bi} > N_{Fe} > N_{Ne} > N_{Pb}$$.

Reason **R**: The radius $$R$$ of the nucleus is related to its mass number $$A$$ as $$R = R_0 A^{1/3}$$, where $$R_0$$ is a constant.

In the light of the above statement, choose the correct answer from the options given below:

Accepted Answer
