The electric field is created by two infinite parallel plates carrying a charge uniformly distributed over the area with a surface density σ1 = -4 nC / m2 and σ2 = -8 nC / m2.The space between the plates is filled with a dielectric with a dielectric constant ε = 4, outside the plates is vacuum. The distance between the plates is 4 cm. Plot the dependence of the field strength and induction along the x-axis, perpendicular to the plates within -5 cm≤x≤ 9 cm. Take the starting point at the point where the first plate is located.
