A muan is an unstable elementary partical whose mass `(mu^(-))` can be captured by a hydrogen nucleus (or proton) to from a muonic atom.
a Find the redius of the first Bohr orbit of this atom.
b Find the ionization energy of the atom.

Answer

A, B, C

Explanation

(a) `r prop (1)/(m)`
`:.r=(r_1^H)/(m) = (0.529xx10^(-10)/(207)`
`=2.55x10^(-13) m`
(b) `E prop m`
`:. Ionization energy of given atom`
=(m)(ionization energy of hydrogen atom) =(207)(13.6 eV)
= 2815.2 eV = 2.81 ke V
