Two concentric spheres of radius 10 cm and 20 cm distributed evenly charges a surface density of 50 nC / m ^ 2 <and -25 nC / m ^ 2. Using Theorem Ostrogradskii-Gause, find the dependence of the electric field intensity of the distance from the center of the sphere for all three areas inside and outside areas and build her schedule.
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
