Assertion : The binding energy per nucleon, for nuclei with atomic mas

1.	Assertion : The binding energy per nucleon, for nuclei with atomic mass number A> 100 decreases with A.Reason : The nuclear forces are weak for heavier nuclei.(a) Both A and R are true and R is the correct explanation of A(b) Both A and R are true but R is not correct explanation of A(c) A is true but R is false(d) A and R are false
Answer» The correct option is(b) Both A and R are true but R is not correct explanation of A. Explanation: The decrease in binding energy per nucleon for heavy nuclei (A> 100) due to increase in coulombrepulsion between the protons insidethenucleus.

Answer»

The correct option is(b) Both A and R are true but R is not correct explanation of A.

Explanation:

The decrease in binding energy per nucleon for heavy nuclei (A> 100) due to increase in coulombrepulsion between the protons insidethenucleus.
