Energy of the Electron & Energy Levels question from NEET 2005 (AIPMT)

Q51NEET 2005 · AIPMTEasy

Energy of the Electron & Energy Levels

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

Show answer and solution

Answer: (a)

In a Bohr orbit $KE = -E$ .
$KE = -(-3.4) = 3.4\text{ eV}$
So the answer is (a) 3.4 eV.
