Assertion:- Kinetic energy of two subatomic particles, having same de-Broglie’s wavelength is same. Reason:- de-Broglie’s wavelength is directly related to mass of subatomic particles. How are both statements false? (Please explain why (especially) assertion is false)

							The two subatomic particles may be diferent or same.If they are same, then their de-Broglie's wavelength will be same. i.e both proton, or both electron etcIf there are different, both will have a different mass than the other,then from our equation$\fn_cm {\color{Red} \lambda }= h/ \sqrt{2m(K.E)}$since  $\fn_cm \lambda$ is same and h is a constant, product of 'm’ and K.E will be same. But for different 'm', KE will be different.  The reason is wrong as $\fn_cm \lambda = h/mv$thus it is inversely proportional to m
