Two particles, A and B, have the same mass, but particle A has a charge of +q and B has a charge of +2q. The particles are accelerated from rest through the same potential difference. Which one has the longer de Broglie wavelength at the end of the acceleration? (a) Particle A, because it has the greater momentum, and, hence, the longer de Broglie wavelength (b) Particle B, because it has the greater momentum, and, hence, the longer de Broglie wavelength (c) Particle A, because it has the smaller momentum, and, hence, the longer de Broglie wavelength (d) Particle B, because it has the smaller momentum, and, hence, the longer de Broglie wavelength (e) Both particles have the same de Broglie wavelength.
