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. Figure 1 of 1 > Do + 9 Ē Review Constants The ink drops have a mass m = 1.00×10-11 kg each and leave the nozzle and travel horizontally toward the paper at velocity v = 21.0 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 Do = 2.30 cm, where there is a uniform vertical electric field with magnitude E8.40×104 N/C. (Figure 1) Part A If a drop is to be deflected a distance d = 0.250 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. Express your answer numerically in coulombs. ► View Available Hint(s) ΕΠΙ ΑΣΦ q= Submit Previous Answers ? C

Your physics assignment is to figure out a way to use electricity to launch a small 6.0-cm-long plastic drink stirrer. You decide that you'll charge the little plastic rod by rubbing it with fur, then hold it near a long, charged wire. When you let go, the electric force of the wire on the plastic rod will shoot it away. Suppose you can charge the plastic stirrer to 16.0 nC and that the linear charge density of the long wire is 1.0 x 10-7 C/m. (Figure 1) Figure < 1 of 1 A 1.0 X 107 C/m +++++++++++ 2.0 cm Plastic stirrer 6.0 cm Part A What is the electric force on the plastic stirrer if the end closest to the wire is 2.0 cm away? Hint: The stirrer cannot be modeled as a point charge, an integration is required. Express your answer with the appropriate units. |μA ?
