Question
(a) If a moving proton and an electron have the same wavelength, then whose velocity will be greater and why?
✓

Answer

(a) According to formula $\lambda=\frac{ h }{ mV }$, when $\lambda$ and h are constant then velocity is inversely proportional to mass, as mass of electron is less than that of proton, hence its velocity will be more.
