Question

How the linear velocity 'v' of an electron in the Bohr orbit is related to its quantum number ' \(n\) ' ?
(A) \(v \propto \frac{1}{n}\)
(B) \(v \propto \frac{1}{n^{2}}\)
(C) \(v \propto \frac{1}{\sqrt{n}}\)
(D) \(v \propto n\)

Answer 1

Ans: (A)
 mvr \(=\frac{n h}{2 \pi}, m v \cdot r_{0} n^{2}=\frac{n h}{2 \pi}, v \propto \frac{1}{n}\)
