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

A

`2:-1`

B

`1:-1`

C

`1:1`

D

`1:-2`

Text Solution

Verified by Experts

The correct Answer is:
B
If the total energy and the kinetic energy of an electron in n-th Bohr radius are `E_n and E_k` respectively,
`E_k=-E_n or, (E_k)/(E_n)=1:(-1)`
