Que.2 Attempt any six questions.Find the de Broglie wavelength of a proton accelerated by a potential ofMass of nroton is1.673x10 27kg)

Answer»

Given, V = 50v

Therefore,

E=qV=1.6×10^−19×50=8×10^−18J

We know, E=p^2/2m

8×10^−18×2×1.673×10−27=p^2

h/λ=(267.68×10−46)^1/2

h/λ= 16.36×10−23

λ=6.62×10^−34/16.36×10^−23

λ=4.04×10^-10 m

Wavelength of proton = 4.04×10^-10 m
