Two thin square flat sheets are placed parallel to each other. The distance between the sheets is much smaller than the size of each sheet, so we can consider the sheets infinite. The sheets are uniformly charged, with surface charge densities σ1 and σ2, respectively. The magnitudes and the signs of these charge densities are not known. To determine σ1 and σ2, you measure the electric force on a test point charge q = 2.00 nC at several locations. You...

A capacitor made of conductive plates (made of metal) is aligned as shown. The plates have a surface area of 2 x 10-1 m2 and are 0.01 m apart from each other. The capacitor is first connected to the voltage source until it is fully charged and produces a potential difference of V0 = 3 kV and then released from the voltage source earlier. If between the two capacitor plates the plastic dielectric material is inserted and fully filling the...
