Given below are two statements: one is labelled as Assertion $\displaystyle \mathbf{A}$ and the other is labelled as Reason RAssertion A : The binding energy per nucleon is practically independent of the atomic number for nuclei of mass number in the range $\displaystyle 30$ to $\displaystyle 170$ .Reason $\displaystyle R$ : Nuclear force is short ranged.
In the light of the above statements, choose the correct answer from the options given below
Official answer
From NTA’s final answer key for this paper.
(1)
Both $\displaystyle \mathbf{A}$ and $\displaystyle \mathbf{R}$ are true and $\displaystyle \mathbf{R}$ is the correct explanation of $\displaystyle \mathbf{A}$
