The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom, is

Options

A. `-1`
B. `2`
C. `1:2`
D. None of these

Answer

A

Explanation

As, `K=(me^(4))/(8epsi_(0)^(2)n^(2)h^(2)h^(2)),E=-(me^(4))/(8epsi_(0)^(2)n^(2)h^(2))`
`implies K=-K implies (K)/(E)=-1`
