A proton, a neutron, an electron and an $\displaystyle \alpha$-particle have same energy. If $\displaystyle \lambda_p, \lambda_n, \lambda_e$ and $\displaystyle \lambda_\alpha$ are the de Broglie's wavelengths of proton, neutron, electron and $\displaystyle \alpha$ particle respectively, then choose the correct relation from the following :
Official answer
(2)
$\displaystyle \lambda_\alpha<\lambda_n<\lambda_p<\lambda_e$
