25. The distance between the plates of a flat capacitor is d = 5 mm, the potential difference is U = 500 V. Determine: 1) the surface charge density on the plates of the capacitor; 2) the surface density of the bound charges on the dielectric, if it is known that the dielectric susceptibility of the dielectric filling the space between the plates, χ = 1.
