Two long straight parallel filaments are at a distance d = 5 cm apart. Uniformly distributed on the filaments with linear densities of charges t (1) = -5 nC / cm and t (2) = -10nKl / cm. Determine the intensity E of the electric field away from the first thread to the distance r (1) = 3 cm and at a distance from the second r (2) = 4cm.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
If you have any questions to address, please. I´ll try to help.
