Question

The mass number of nucleus having radius equal to half of the radius of nucleus with mass number 192 is :

Accepted Answer

$$\begin{aligned}
& \mathrm{R}_1=\frac{\mathrm{R}_2}{2} \
& \mathrm{R}_0\left(\mathrm{~A}_1ight)^{1 / 3}=\frac{\mathrm{R}_0}{2}\left(\mathrm{~A}_2ight)^{1 / 3} \
& \mathrm{~A}_1=\frac{1}{8} \mathrm{~A}_2 \
& \mathrm{~A}_1=\frac{192}{8}=24
\end{aligned}$$
