De broglie postulated that for a particle with a momentum p, its corresponding wavelength is λ = n, where h is the planck's constant. assuming that a particle has a mass of m and a total kinetic energy of e, express the de broglie wavelength of this particle as a function of e, m, and h only. (ii) given that f(x) [in(5x2)]6, then determine the value of f'(2).
