Bohr proposed his atomic model based on ...

Bohr proposed his atomic model based on Planck.s quantum theory and derived following relations for one electron system in C.G.S. units : For H -atom : `r_(n) = n^(2) xx r_(1), E_(n) = E_(1) xx Z^(2), u_(n) = (u_(1))/(n), u_(1) = 2.19 xx 10^(8) cm//sec., E_(1) = -13.6eV`
For 1 electron system, other than H `r_(n) = (n^(2) xx r_(1H))/(Z), E_(N) = (E_(1H) xx Z^(2))/(n^(2)), u_(n) = (u_(1H) xx Z)/(n)`. Later on de Broglie proposed the dual nature of electron and put forward his wave concept. The wave length of electron in an orbit was given `lambda` = h/mu
The potential energy of electron in`3^(rd)` Bohr orbit of H-atom is :

A

`1.0 xx 10^(-9)`

B

`2.0 xx 10^(-7)`

C

`1.0 xx 10^(-7)`
