Expert Solution
Introduction:
  • The density of a nucleus is found to be dependent on the distance from the center. The density is found to be constant till a certain distance from the center and then decreases gradually.

 

  • The radius of a nucleus is defined as the distance from the center where the density reduces to half its original value. From experimental data, the nuclear radius is found to be,

R=r0A13

Here r0 is a constant with a value of 1.25 fm and A is the mass number.
