Question

A moving proton and electron have the same de-Broglie wavelength. If K and P denote the K . E . and momentum respectively. Then choose the correct option :, K p > K e and P p = P e, K p K e and P p = P e, K p K e and P p P e, K p = K e and P p = P e

λ d e b = h p = h 2 m K E If λ is same the P will be same K E ∝ 1 / m m p > m e ⇒ K p K e
