Fine structure constant , for electrons defined as v/c where v is the speed of electrons around the atomic nucleus and c is the speed

Fine structure constant α, for electrons defined as α≡v/c where v is the speed of electrons around the atomic nucleus and c is the speed of light. The negative Muon particle (μ ^- ) is a subatomic particle that has the type and magnitude of the charge equal to an electron, but has a mass 207 times the mass of the electron. These negative muons can be attracted by protons and form hydrogen-like structures called muonic hydrogen atoms. Determine:

a. The velocity of muons around the proton!

b. Fine structure constants for muon in muonic hydrogen atom!
