Question 225: Atoms & Nuclei

Question

Which of the following figure represents the variation of $${l_n}\left( {{R \over {{R_0}}}} \right)$$ with $${l_n}A$$ (if R = radius of a nucleus and A = its mass number)

Accepted Answer

We know that
$$R = {R_0}{A^{1/3}}$$
$$ \Rightarrow \underbrace {\ln \left( {{R \over {{R_0}}}} \right)}_y=\underbrace {{1 \over 3}}_m\underbrace {\ln (A)}_x$$
$$\Rightarrow$$ Straight line
