Question

Answer the following.
(i) Why is the binding energy per nucleon found to be constant for nuclei in the range of mass number (A) lying between 30 and 170?
(ii) When a heavy nucleus with mass

Answer 1

Dear Student ,

(1)The binding energy is a very short order range force.

So beyond a certain amount of range the force has no influence beyond that. That's why after

certain number the binding energy per nucleon do not change even if we add more nucleons

(2) It is so because, when the nucleus will decompose into lighter nuclei, there will be some mass lost which comes out in the form of energy.
