Atoms and Nuclei question

2018 · 15 Apr · Shift 2 · Q69

JEE MainPhysicsAtoms and NucleiMCQ+4 / −1
Muon (μ−\mu -μ−) is a negatively charged (|q| = |e|) particle with a mass m μ\muμ= 200 me, where me is the mass of the electron and e is the electronic charge. If μ−\mu -μ− is bond to a proton to form a hydrogen like atom, identify the correct statements. (A) Radis of the muonic orbit is 200 times smaller than that of the electron. (B) The speed of the μ−\mu -μ− in the nth orbit is 1200{1 \over {200}}2001​ times that of the electron in the nth orbit. (C) The ionization energy of muonic atom is 200 timesmore than of an hydroen atom. (D) The momentum of the muon in the nth orbit is 200 times more than that of the electron.
