Electrons that are initially at rest are accelerated by a voltage, V , which produces a monoenergetic beam. This beam is directed at a double slit apparatus with slits of width b and with a slit separation, d. A bank of electron detectors is a distance L beyond the double slit. The first minimum in the electron count accurs at detector X. How far is detector X from the the center of the interference pattern
