Product description
328. On two coaxial infinite cylinders radiuses of R and 2R evenly distributed charges with area densities σ1 and σ2. It is required: 1) using Ostrogradsky´s theorem — Gauss: to find dependence of E (x) intensity of electric field on distance for three areas: I, II and III. To accept σ1 = –2σ, σ2 = σ; 2) to calculate intensity E in the point remote from an axis of cylinders on r raskstoyaniye, 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).
