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.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of the assertion
  3. CIf assertion is true, but reason is false
  4. DBoth assertion and reason are false statements.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of the assertion

Step-by-step solution

The decrease in binding energy per nucleon for heavy nuclei (A>100) due to increase in coulomb repulsion between the protons inside the nucleus.
