    How Does an Electrostatic Ink-Jet Printer Manipulate Charged Ink Drops?

    You want me to show my attempt at finding accereration? -20^2=2(a)(.02+003), solve for a, a =8696 m/s^2, the .003 being the middle of plate if i was to go further and find E, I use the fact that f=eq, a=eq/m, and so e would be 4.95*10^-8

    How Does an Electrostatic Ink-Jet Printer Manipulate Charged Ink Drops?

    Yes, I do, I can see that I can find acceleration and then I could find E, but its not the right E, so I am not sure how it relates. I need guidance.

    How Does an Electrostatic Ink-Jet Printer Manipulate Charged Ink Drops?

    1. 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 30.0 (mu)m diameter drops of ink, charges them by...

    Surface Charge Density and high-speed proton beam

    I am having NO LUCK. What kinematics formula specifically are you using? I have taken the velocity the electron exits , divided by the distance to get the time and then using the velocity and time using the equation, vy=vo+.5(eE/m)t^2, substituting a with the formula and also tried solving for...

    Surface Charge Density and high-speed proton beam

    There is a problem with the hint! Apparently we arent covering Energy for a couple of chapters and I am supposed to use Forces. We knew energy it would be really easy but since I don't and it won't be applicable on the test. I need to understand how to solve without Energy. I would be sorry...

    Surface Charge Density and high-speed proton beam

    You have a summer intern position at a laboratory that uses a high-speed proton beam. The protons exit the machine at a speed of 2.10 times 10^6 m/s, and you've been asked to design a device to stop the protons safely. You know that protons will embed themselves in a metal target, but protons...

    Uniform Charge Density: Homework Solution

    Homework Statement ou've hung two very large sheets of plastic facing each other with distance d between them, as shown in the figure View Figure . By rubbing them with wool and silk, you've managed to give one sheet a uniform surface charge density eta_1= - \eta _{0} and the other a...
