Задача 30046.

A metal ball with radius R1, carrying charge q=1 nC, is surrounded by a concentric hollow metal ball with inner radius R2 and outer R3. The charge on the outer sphere is zero. Construct a plot of field strength versus distance from the center of the balls. Find the potential of the balls if the potential is zero at infinity.

A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I will try to help.
