IF Ep and Ek represent potential energy ...

IF `E_p and E_k` represent potential energy and kinetic energy respectively of an orbital electron, then according to Bohr's theory.

A

`E_k=- E_p/2`

B

`E_k=E_p`

C

`E_k=2E_p`

D

`E_k=-2E_p`

Text Solution

Verified by Experts

The correct Answer is:
A
For all the electrons in a given orbit,
`E=-K=U/2`
`therefore K=- U/2`
`therefore E_k=- E_p/2` (`because` Here `K=E_k` and `U=E_p` )
