Q160 / 160 · AP EAMCET 2020 (23 Sep Shift 1) · Physics

Minimum excitation potential of Bohr's first orbit of Hydrogen atom is_____.

  • A
    3.6 V
  • Correct answer
    B
    10.2 V
  • C
    13.6 V
  • D
    3.4 V

Solution

Minimum excitation energy of Bohr's first orbit of Hydrogen atom is given by, 

∆U=13.61-122 eV⇒∆U=10.2 eV

So minimum excitation potential of Bohr's first orbit of Hydrogen atom is 10.2 V

 

Hence, the correct answer is option: 'B'.
