NEET 2019 Physics Bohr's Model MCQ Question with Solution

The total energy of an electron in an atom in an orbit i $s^{-3}$ .4 eV. Its kinetic and potential energies are, respectively

A

3.4 eV, -6.8 eV

B

3.4 eV, -3.4 eV

C

-3.4 eV, -3.4 eV

D

-3.4 eV, -6.8 eV

Correct Answer

Option A

Detailed Explanation

In an atom, the total energy E = KE + PE. For an electron, KE = -PE/2. Given E = -3.4 eV, KE = 3.4 eV and PE = -6.8 eV.
