An ink-jet printer works by steering charged ink drops to theright place on the page by passing moving drops through a uniformelectric field that deflects them by the appropriate amount. Figure23-47 shows an ink drop approaching the field region which haslength [IMG: scripted l] and width /d/ between the charged platesthat establish the field. Find an expression for the minimum speeda drop with mass /m/ and charge /q/ must have if it is to getthrough the region without hitting either plate. (Ignore theeffects of gravity and assume that the droplet begins at height/d2. Use the following as necessary: [IMG: scripted l] /d//m/ /q/ and /E/.)
