motion of a charged particle in an E field

motion of a charged particle in an E field One type of ink-jet printer, called an electrostatic ink-jet printer, forms the letters by using deflecting electrodes to steer charged ink drops up and down vertically as the ink jet sweeps horizontally across the page. The ink jet forms 28.0 μm −diameter drops of ink, charges them by spraying 800,000 electrons on the surface, and shoots them toward the page with a horizontal velocity of 15.0 m/s. Along the way, the drops pass through the long axis of two horizontal, parallel electrodes that…
