In an inkjet printer, letters are built up by squirting dropsof ink at the paper from a rapidly moving nozzle. The pattern onthe paper is controlled by an electrostatic valve that determinesat each nozzle position whether ink is squirted onto the paper or not. The ink drops, 15.9 mm in radius,leave the nozzle and travel toward the paper at 18.1 m/s. The dropspass through a charging unit that gives each drop a positive chargeq when the drop loses some electrons. The drops then passbetween parallel deflecting plates 2 cm in length where there is auniform vertical electric field with magnitude 76000 N/C. If a dropis to be deflected 0.3 mm by the time it reaches the end of the deflection plate, what magnitude of charge must be given to the drop? (Assume that the density of the ink drop is the same as that of water, 1000 kg/m^3.)
