Two conductors in the form of half rings lie in the same plane and have a common center. Determine the tension in the center of half-rings for the following data: the radius of the first half-rings 10 cm, the second - 20 cm, the currents flow in the same direction and the current is respectively equal to 1 and 4 A. Field of the conductive wires are not taken into account.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
