    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) `` 25: 16 ``
    (B) `` 1: 1 ``
    (C) `` 4: 5 ``

    (D) `` 5: 4 ``
    digAnsr:   D
    Ans : 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} ``
