alleryStart learning →The binding energy per nucleon stays nearly constant in the middle range because the nuclear force is:
AElectrical
BShort ranged
CLong ranged
DVery weak
Answer & Solution
Correct answer: B. Short ranged
1. Each nucleon feels only its close neighbours.
2. Adding more nucleons far away changes nothing.
3. So the nuclear force is short ranged.
