In the Bohr model of the hydrogen atom, the ratio of the kinetic energy to the total energy of the electron in a quantum state `n` is ……..

Options

A. `-1`
B. `+1`
C. `1/n`
D. `1/n_(2)`

Answer

A

Explanation

According to the Bohr model
` -|T.E|/2=+|KE|/2=-(PE),
Where T.E= (+me^(4))/(8in_(0)^(2)n^(2)h^(2))
K.E= +(me)^(4)/(8in_(0)^(2)n^(2)h^(2))Rightarrow(KE)/(TE)=-1`
