What should be the order of arrangement of de-Broglie wavelength of electron (\\lambda_{{e}}), an \\alpha-particle (\\lambda_{\\alpha}) and proton (\\lambda_{{p}}) given that all have the same kinetic energy ? [25 Jul 2021 Shift 1]

Correct Answer is : λe>λp>λα

\\lambda_{{e}}=\\lambda_{{p}}=\\lambda_{\\alpha}

\\lambda_{{e}} < \\lambda_{{p}} < \\lambda_{\\alpha}

\\lambda_{{e}}>\\lambda_{{p}}>\\lambda_{\\alpha}

\\lambda_{{e}}=\\lambda_{{p}}>\\lambda_{\\alpha}
