13.Nuclei
medium
A 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:
A
$4: 5$
B
$5: 4$
C
$25: 16$
D
$1: 1$
(NEET-2022)
Solution
Nuclear Radius :
$R=R_{0}(A)^{1 / 3}$
$\frac{R(125)}{R(64)}=\frac{R_{0}(125)^{1 / 3}}{R_{0}(64)^{1 / 3}}=\frac{5}{4}$
