MCQ
Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$

Assertion $A:$ The binding energy per nucleon is practically independent of the atomic number for nuclei of mass number in the range $30$ to $170$.

Reason $R$ : Nuclear force is short ranged.

In the light of the above statements, choose the correct answer from the options given below on

  • A
    Both $A$ and $R$ are true but $R$ is NOT the correct explanation of $A$
  • B
    $A$ is true but $R$ is false
  • C
    $A$ is false but $R$ is true
  • Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

Answer

Correct option: D.
Both $A$ and $R$ are true and $R$ is the correct explanation of $A$
d
Binding energy per nucleon is almost same for nuclei of mass number ranging $30$ to $170$.
