Question:

Soot particles, from incomplete combustion in diesel engines, are typically 15 nm in diameter and have a density of 1200 kg/m³. FIGURE P39.45 shows soot particles released from rest, in vacuum, just above a thin plate with a 0.50-Î¼m-diameter hole€” roughly the wavelength of visible light. After passing through the hole, the particles fall distance d and land on a detector. If soot particles were purely classical, they would fall straight down and, ideally, all land in a 0.50-Î¼m-diameter circle. Allowing for some experimental imperfections, any quantum effects would be noticeable if the circle diameter were 2000 nm. How far would the particles have to fall to fill a circle of this diameter?
