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:

Solution & Step-by-step Explanation

The radius of a nucleus is given by R = R_{0} A^{1/3}, where A is the mass number.Ratio \frac{R _{1}}{R _{2}} = (\frac{A _{1}}{A _{2}})^{1/3} .Given A_{1} = 125 and A_{2} = 64 . \frac{R _{1}}{R _{2}} = (\frac{125}{64})^{1/3} = \frac{5}{4} The ratio is 5 : 4 .

Try it yourself before checking the explanation above.
