Задача 30079.

Two long straight parallel filaments are at a distance d = 10 cm apart. Uniformly distributed on the filaments with linear densities of charges -2 nC / cm and 4 nC / cm. To determine the electric field intensity at a point remote from the first thread to the distance of 6 cm and at a second distance of 8 cm.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
