Muon (μ^ -1 ) is negatively charged (|q|=|e|) with a mass m_μ=200...
Muon is negatively charged with a mass , where is the mass of the electron and e is the electronic charge. If is bound to a proton to form a hydrogen like atom, identify the correct statements
(A) Radius of the muonic orbit is 200 times smaller than that of the electron
(B) the speed of the in the th orbit is times that of the election in the nth orbit
(C) The lonization energy of muonic atom is 200 times more than that of an hydrogen atom
(D) The momentum of the muon in the nth orbit is 200 times more than that of the electron
Options
- A(A), (B), (D)
- B(B), (D)
- C(C),(D)
- D(A), (C), (D)
Correct answer
D. (A), (C), (D)
Step-by-step solution
(e^{-} \mathrm{H}\frac{+m e^4}{8 \epsilon_0^2 n^2 h^2}\frac{200 m e^4}{8 \epsilon_0^2 n^2 h^2}=\mathrm{H}\frac{n h}{2 \pi}$Hence (A), (C), (D) are correct.
