In an inkjet printer, letters are built up by squirting drops of ink at the paper from a rapidly moving nozzle. The ink drops, which have a mass of 1.3 x 10^-8 g each, leave the nozzle and travel toward the paper at 19 m/s, passing through a charging unit that gives each drop a positive charge q by removing some electrons from it. The drops then pass between parallel deflecting plates 2.0 cm long where there is a uniform vertical electric field with magnitude 8.5 x 10^4 N/C. If a drop is to be deflected 0.25 mm by the time it reaches the end of the deflection plates, what magnitude of charge must be given to the drop?
