Q18.Imagine that the electron in a hydrogen atom is replaced by a muon (μ). The mass of muon particle is 207 times that of an electron and charge is equal to the charge of an electron. The ionization potential of this hydrogen atom will be:- (1) 13. 6 eV (2) 2815. 2 eV (3) 331. 2 eV (4) 27. 2 eV JEE Main 2021 (18 Mar Shift 1) JEE Main Previous Year Paper
What This Question Tests
This question assesses the understanding of how the ionization potential in a hydrogen-like atom changes when the mass of the orbiting particle (electron) is replaced by another particle (muon), which affects the reduced mass and thus the energy levels.
Concepts Tested
Formulas Used
