Calculate the velocity of an electron in the first Bohr orbit of a hydrogen atom

Text Solution

Verified by Experts

Assume `n = 1`, take `Z = 1`, and insert the values of the constants to obtain
`V_(1) = ((2)(3.14)(1)(4.8xx10^(-10)esu)^(2))/((1)(6.63xx10^(-27)erg s))`
`= 2.18 xx 10^(8)cm s^(-1)`
`= 2.18 xx 10^(6) m s^(-1)`
