If the electron of a hydrogen atom is present in the first orbit. The total energy of the electrons is

A

`(-e^2)/(r)`

B

`(-e^2)/(r^2)`

C

`(-e^2)/(er)`

D

`(-e^2)/(2r^2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`E = PE + KE implies (-ze^2)/(r) + (ze^2)/(2r)`
`E = (-ze^2)/(2r) implies (-e^2)/(2r)`
