हिन्दीA nucleus of mass number 189 splits into two nuclei having mass number 125 and 64. The ratio of radius of two daughter nuclei respectively is:
Correct answer · Option 1
5 : 4
Explanation
Nuclear radius \( R \propto A^{1/3} \). Therefore, \( \frac{R_1}{R_2} = (\frac{A_1}{A_2})^{1/3} = (\frac{125}{64})^{1/3} = \frac{5}{4} \).
