An electron, helium ion ( He ⁺⁺ ) and proton having the same kinetic energy. The relation between their respective de-Broglie wavelengths _ , _ He ⁺⁺ and _p is

Options

  1. A_e _p _ He ⁺⁺
  2. B_e _ He ⁺⁺ _
  3. C_e _p _ He ⁺⁺
  4. D_e _ He ⁺⁺ = _p

Correct answer

A. _e _p _ He ⁺⁺

Step-by-step solution

de-Broglie wavelength is given by array l = h p = h 2 m k 1 m ( k_e=k_p=k_ He ⁺⁺ ) As, m_ He ⁺⁺ m_p m_ _ He ⁺⁺ _p _ _ _p _ He ⁺⁺ array
