If the energy of first Bohr's orbit is `-2.17 xx10^(-11)` ergs, then the energy of fifth Bohr orbit is

A

`-2.17xx10^(-11)` ergs

B

`-8.68xx10^(-13)` ergs

C

`-5.42xx10^(-10)` ergs

D

`-2.08xx10^(-11)` ergs

Text Solution

Verified by Experts

The correct Answer is:
B
Energy of first Bohr orbit =`-2.17xx10^(-11)`ergs
`therefore` Energy of 5th orbit `=(-2.17xx10^(-11))/25`
`= -0.0868xx10^(-11)` ergs
