The ink drops have a mass m = 1.00x10'11 kg each and leave the nozzle and travel horizontally toward the paper at velocity v = 15.0 m/s . The drops pass through a charging unit that gives each drop a positive charge q by causing it to lose some electrons. The drops then pass between parallel deflecting plates of length D0 = 1.85 cm , where there is a uniform vertical electric eld with magnitude E = 7.55x104 N/C . (gure 1) In an inkjet printer, letters and images are created by squirting drops of ink horizontally at a sheet of paper from a rapidly moving nozzle. The pattern on the paper is controlled by an electrostatic valve that determines at each nozzle position whether ink is squirted onto the paper or not. V Part A If a drop is to be deflected a distance d = 0.270 mm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop? Assume that the density of the ink drop is 1000 kg / m3 , and ignore the effects of gravity. Figure 1 of 1 Express your answer numerically in coulombs. b View Available Hint(s) Provide Feedback Next )
