The gyromagnetic ratio of an electron in an H-atom, according to Bohr model, is

Answer»

independent of which orbit it is in.
negative
positive
increases with the QUANTUM number n.

Solution :Gyromagnetic ratio, `mu_(l)=-e/(2m_(e))l`
Gyromagnetic ratio = `("Magnetic moment of e")/("ANGULAR MOMENTUM of e")`
`mu_(l)=M_(e)/L_(e)`
= `(-evr)/(2m_(e)VR)" "(becauseM_(e)=(-evr)/2" "L_(e)=m_(e)vr)`
`mu_(l)=(-e)/(2m_(e))`
Magnetic moment doesn.t depend on velocity of electron. But only depends on charged particle e and it is negative. So, option (A) and (B) are TURE.
