In a hypothetical Bohr hydrogen atom, the mass of the electron is double then

A

`E_(0)=-27.2eV,r_(0)=a_(0)//2`

B

`E_(0)=-27.2eV,r_(0)=a_(0)`

C

`E_(0)=-13.6eV,r_(0)=a_(0)//2`

D

`E_(0)=-13.6eV,r_(0)=a_(0)`

Text Solution

Verified by Experts

The correct Answer is:
A
As, `rprop(1)/(m)`
`therefore r_(0)=(1)/(2)a_(0)`
As `Epropm`
`therefore E_(0)=2(-13.6)=-27.2eV`
