Answer & Solution
Correct Answer
(D) (A)-(IV), (B)-(I), (C)-(III), (D)-(II)
Step-by-step Solution
Detailed explanation
(A) Orbital radius of electron: \(r_n \propto n^2\) (B) Orbital velocity of electron: \(v_n \propto \frac{1}{n}\) (C) Orbital frequency of electron: \(f_n = \frac{v_n}{2 \pi r_n} \propto \frac{1/n}{n^2} \propto \frac{1}{n^3}\) (D) Angular momentum of electron: \(L_n \propto n\)…
