Question Paper from: IIT JEE Main 2021 TestSeries Paper 1

If E₁, E₂, and E₃ represent respectively the kinetic energies of an electron, $α -$ particle, and a proton each having same de Broglie's wavelength then

E₁ > E₃ > E₂

E₂ > E₃ > E₁

E₁ > E₂ > E₃

E₁ = E₂ = E₃

Solution:

Chapter Name: Atomic Structure

Difficulty Level: Moderate

$λ = \frac{h}{2 k E m}$

Where m $\to$ $M_{e} / M_{p} / M_{α - p a r t i c l e}$
