The enegry of the following is not ture regarding cathode rays?

A

zero

B

`-54.4 eV`

C

`-13.6 eV`

D

`-26.5 eV`

Text Solution

Verified by Experts

The correct Answer is:
B
According to Bohr's theory, the energy of electron in the `nth` orbit is given as ltbrltgt `E_(n) = (Z^(2)E_(1))/(n^(2))`
Therefore,
`E_(1) = ((2)^(2)(-13.6eV))/((1)^(2)) =- 54.4eV`
