HC/2OZZI Use the information and diagram below to answer question 10. Ink jet printers work by sending a small drop of ink towards the media to be printed upon (e.g., paper). Ultra precise control over the ink drops is needed in order to effectively print. Each small ink drop travels past an electrode that gives it a charge. The charged ink drop passes through a uniform electric field generated by parallel plates. If a gap in the printing is needed (e.g., a white space) the plates are charged so the ink drop will continue to travel directly through to the "gutter". When the ink drop is used to form part of a letter or a picture on the media, the plates are charged and the ink drop is forced to move upwards, past the gutter to the print media. ink nozzle charging electrode gutter media (e.g., paper) Glossary of terms Ink nozzle: Produces a small drop of ink travelling at a constant velocity. Charging electrode: Charges each of the ink drops. Deflection electrode: Produces an electric field so that the drops will deflect. Gutter: Collects the unused ink. Media: The substance (e.g., paper) to be printed on. 10. Draw a free-body diagram for an oil droplet that travels to the a. gutter. b. paper. 11. A proton moving horizontally at 2.10 x 106 m/s enters a 200 N/C electric field exactly halfway between two horizontal parallel plates as shown in the diagram. Determine the vertical displacement of the proton as it travels between the plates. 20 cm 10 cm p* vertical displacement
