Question:

If radius of the $Al _{13}^{27}$ nucleus is estimated to be 3.6 Fermi then the radius of $Te_{52}^{125}$ nucleus be nearly

Options:

4 fermi

5 fermi

6 fermi

8 fermi

Correct Answer:

6 fermi

Explanation:

$R = R_0 A^{1/3}$

$\frac{R_2}{R_1} = {\frac{A_2}{A_1}}^{1/3}$

$R_2 = 3.6 \times \frac{5}{3} = 6 fermi$
