A beam of electrons passes through a narrow hole and then strikes a screen. After the beam passes through the hole, it is found that the beam spreads because the electrons have acquired an average momentum of p transverse (perpendicular) to the direction of their original motion. If the hole is made larger, does the average transverse momentum become larger, become smaller, or stay the same?
