l7. Electrons are accelerated through a potential difference, Vn = 120 V, before exiting and being subjected to a new set ofparallel plates. The electrons enter this region 5.0 cm from the bottom plate, and hit this bottom plate a distance of 5.0 cm in. lfthe total plate separation ofthis second set ofplates is 8.0 cm, determine the voltage of the second source AND draw this source in, clearly showing the positive vs negative terminals of the battery.
