A proton `(mass = 1.66 xx 10^(-27)kg)` is moving with kinetic energy `5 xx 10^(-27) J` calculate the de Broglie wavelength associated with it? `(h = 6.6 xx 10^(-34)Js)`

Answer

`1.62 xx 10^(-7) m`

Explanation

Mass of proton `= (1.008 xx 10^(-3))/(6.02 xx 10^(23)) kg = 1.67 xx 10^(-27) kg`
Further proceed as in Solved Problem 3.
