3. The electric field is created by infinite parallel plates carrying a charge uniformly distributed over the area with surface densities δ1 = 10 nC / m ^ 2, b2 = 3 nC / m ^ 2. The distance between the plates is d = 6 mm. Determine: a) the strength of the electric field outside and between the plates; b) the potential difference between the plates; c) the density of the surface charge and the density of the induced charge on both sides of each plate. Build graphs of changes in E and f along a line perpendicular to the plates. How will the graphs change if the distance between the plates is doubled?
