1. Electrostatics and Basic Charge Manipulation 1.1. Electrostatics - a hard, but interesting question! You will need help with this. In a particular model of photocopier, the toner particles have:- an average diameter of 5 µm a mass of 2.0 x 10-13 kg are each given a charge of 100, 000 electrons. (The charge on an electron is 1.6x 10-19 Coulombs). paper (a) 75μm toner particle 25μm metal drum fictitious positive "image" charge toner particle (b) E E-QE Fig 1.1 (a): Photocopier drum, paper and toner particle - cross-section (b) how the forces on the toner particle can be found (see question). Fig. 1.1(a) shows the general arrangement at the point where toner is transferred from the photoconductor drum to the paper. Estimate the potential to which the surface of the paper must be charged in order to attract an isolated toner particle from the surface of the drum to the paper.
