Questions
Consider 3rd orbit of He+ (Helium) Using non relativistic approach, the speed of electron in this orbit will be (given K = 9 × 109 constant, Z = 2 and h= 6.6×10-34 Js) (Plancks constant=h)
detailed solution
Correct option is D
We know that velocity V=e24πKh2n=1.6 x 10-1924 x 227 x 9 x 109 x 6.6 x 10-34 x 23 =1.46 x 106 ; (shortcut) V=c137zn =3 x 108137 x 23=2137 x 108=1.46 x 106Talk to our academic expert!
