Two infinite uniformly charged cylinders are arranged as shown in the figure (the axis of the right cylinder is perpendicular to the plane of the drawing). The linear charge density of the right cylinder is -10^-7 C/cm, the linear charge density of the left cylinder is 10^-7 C/cm; a = 10 cm. The environment is air. Determine: field strength at points A and B; the work of moving a charge of 10^-8 C from point A to point B. Assume that the distribution of charges is not disrupted by interaction.

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