Задача 30739.

Two concentric metal charged spheres with radii of 5 and 10 cm carry charges 3 and -1CL, respectively. Find the intensity and potential of the electrostatic field at points lying from the center of spheres at distances of 3.6 and 12 cm. Build a graph of the dependence of the tension and potential on the distance.
