The radius of

{}_{13}^{27}X

nucleus is

R

. The radius of

{}_{53}^{125}Y

nucleus will be

Solution: 👈: Video Solution

R = R_0 A^{1/3}

\text{ For X, } R = R_0 (27)^{1/3}

\text{ Or, } R = 3 R_0

\therefore R_0 = \frac{R}{3}

\text{ For Y, } R' = R_0 (125)^{1/3}

\text{ Or, } R' = 5 R_0

\therefore R' = \frac{5R}{3}
