MCQ
Energy of the electron in Bohr's orbit is equal to ?
  • A
    Potential energy only.
  • B
    Kinetic energy only.
  • Sum of potential and kinetic energy.
  • D
    difference of kinetic and potential energy.

Answer

Correct option: C.
Sum of potential and kinetic energy.
Energy of electron in Bohr orbit is equal to sum of kinetic and potential energy.
$\triangle \ce{E = KE + PE}$
Because of orbital energy is $PE$ and electron revolving energy is kinetic energy.
