PhysicsEasysingle choice

The total energy of an electron in the first excited state of hydrogen atom is about $- 3.4 eV$ . Its kinetic energy in this state is:NEET 2005

Options:

Answer:

Solution:

$K . E . = \frac{1}{2} P . E$ But P.E is negative $∴ Total energy K . E = \frac{1}{2} P \cdot E - P \cdot E = - \frac{P \cdot E}{2} = - 3.4 eV = + 3.4 eV$
