Problem 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.
Detailed solution with a brief record of the conditions, formulas and laws used in the solution, derivation of the calculation formula and answer.
