(a) Using the Bohr's model, calculate the speed of the electron in a hydrogen atom in the n=1,2 and 3 levels. (b) Calculate the orbital period in each of these levels.

Explanation

(a) `2.18 xx 10^(6) m//s , 1.09 xx 10^(6) m//s , 7.27 xx 10^(5) m//s`
(b) `1.52 xx 10^(-16) s, 1.22 xx 10^(-15) s , 4.11 xx 10^(-15) s`.
