The radius of the second Bohr orbit for hydrogen atom is (Planck's constant, h = 6.6262 xx 10^(-34) Js mass of electron = 9.1091 xx 10^(-31) kg charge of electron, e = 1.60210 xx 10^(-19) C permitivity of the vacuum, in_(0) = 8.854185 xx 10^(-12) kg^(-1) m^(-3) A^(2))

Answer»

`0.529 Å`
`2.12 Å`
`1.65 Å`
`4.76 Å`

SOLUTION :`r = a_(0) xx (N^(2))/(Z)` (`a_(0) =` Bohr radius)
`:. r = 0.529 xx (2^(2))/(1) = 0.529 xx 4 Å = 2.12 Å`
