Question

Assertion :For $n$ = 3, $\ell$ may be 0, 1 and 2 and m may be, 0 , $\pm$1, and 0, $\pm$1 and $\pm$2 Reason: For each value of $n$, there are 0 to ($n$ - 1) possible values of $\ell$ and for each value of $\ell$, there are 0 to $\pm l$ values of $m$

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

As we know,

Value of $\ell =0\to n-1$
Value of $m=-\ell \to +\ell$

For $n=3$, $\ell$ may be $0,1$ and $2$ and $m$ may be $0$ , $\pm$$1$, and $0$, $\pm$$1$and $\pm$$2$.

Hence, option $A$ is correct.
