QNEET-2019-Ph-821: NEET 2019 Physics - Class 12 NEET-2019-Ph-821 Solution: The total energy of an electron in an atom in an orbit is -3.4…
The total energy of an electron in an atom in an orbit is -3.4 eV. Its kinetic and potential energies are respectively. 3.4 eV -6.8 eV 3.4 eV 3.4 eV -3.4 eV -3.4 eV -3.4 eV -6.8 eV
Multiple Choice Options
- 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
Step-by-Step Verified Solution
Apply Bohr's Atomic model for H-atom
KE = �T.E and PE = 2T.E
Given, T.E = �3.4 eV
_ KE = +3.4 eV and PE = -6.8 eV
