{E_1},{E_2}

and

{E_3}

represents kinetic energy of electron,

\alpha -

particle and proton respectively (having same De Broglie wavelength) then

View answer and explanation

Correct option: A

{E_1} > {E_3} > {E_2}

Option A (

{E_1} > {E_3} > {E_2}

) is correct because for the same de Broglie wavelength, kinetic energy is inversely proportional to mass, and the electron has the smallest mass, followed by the proton, and then the alpha particle.
