There are many installations that make use of high-voltage sources for particular applications. For example, sandpaper is often produced by attracting the abrasive particles using voltages in excess of 100 kV to the paper after applying a layer of glue. Consider a system of this type shown in figure 2. 100 kV 2m Paper with glue applied d=0.3 m Plate Abrasive particles d₂ C₂ d₁ C₁ To microprocessor Figure 2: A small capacitor used as a voltage sensor in a sandpaper production machine The high-voltage supply is applied between the top and bottom surfaces, which are 2 m long, 1.2 m wide, and separated 30 cm apart, forming a capacitor. The abrasive particles are placed on the bottom surface and attracted to the top, sticking to the paper. A small plate of area S is placed at a small distance from the lower conducting surface. The potential difference between the plate and ground is connected to a microprocessor to monitor the high voltage across the plate. If the value of the input voltage is 100 kV, what must be the distance of the small plate from the bottom surface if the microprocessor operates at 5 V?
