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:
  1. 4:5
  2. 5:4
  3. 25:16
  4. 1:1

Solution

The relation between radius R of nuclei and mass number A is given by, R=R0A13, where R0 is fermi constant.

Thus, R1R2=A1A213=1256413=54.
