हिन्दीThe total energy of an electron in an atom in an orbit is \( -3.4\text{ eV} \). Its kinetic and potential energies are, respectively
Correct answer · Option A
\( 3.4\text{ eV}, -6.8\text{ eV} \)
Explanation
For an electron in an orbit, Total Energy \( E = -3.4\text{ eV} \). Kinetic Energy \( K = -E = 3.4\text{ eV} \). Potential Energy \( U = 2E = 2 \times (-3.4) = -6.8\text{ eV} \).
