Product description
323. On two concentric spheres the radius of R and 2R evenly distributed charges with area densities σ1 and σ2 (fig.). It is required: 1) using Ostrogradsky´s theorem — Gauss, to find dependence E (x) intensity of electric field from distance for three areas: I, II and III. To accept σ1 =–4σ, σ2 = σ; 2) to calculate intensity E in the point remote from the center on r distance, and to specify the direction of a vector of E. Prinyat σ = 50 nKl/sq.m, r = 1,5R; 3) to construct the schedule of E (x).
