NEET Solved Paper 2019 Question 37
Question: The total energy of an electron in an atom in an orbit is -3.4 eV. Its kinetic and potential energies are, respectively- [NEET 5-5-2019]
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
Show Answer
Answer:
Correct Answer: A
Solution:
- Total energy = - [K.E]
$ \therefore K.E.=+3.4eV $ Potential energy= -2 (Total energy) = -6.8 eV
