84. The space between the plates of a flat capacitor is filled with a dielectric whose dielectric susceptibility is χ = 0.08. The distance between the plates d = 5 mm. A potential difference U = 4 kV is applied to the capacitor plates. Find the surface density of the bound charges σb on the dielectric and the surface density of the charges σb on the plates of the capacitor.
