Question

Statement I: The binding energy per nucleon, for nuclei with atomic mass number A > 100, decreases with A.

Statement II: The forces are weak for heavier nuclei. In the light of the above statements, choose the most appropriate from the options given below.

Options

• Both the Statements are true and Statement II is the correct explanation of Statement I.

• Both the Statements are true but Statement II is not the correct explanation of Statement I.

• Statement I is true but Statement II is false.

• Both the Statements are false.

Answer 1

Statement I is true but Statement II is false.

Explanation:

Statement I is true because the binding energy per nucleon generally decreases with increasing atomic mass number (A) for nuclei with A > 100.

Statement II is false because nuclear force is same for all nuclei.
