In the isolated ring conductor radius of 25 cm flowing current of 15 A. Two straight infinitely long conductor - one in the plane of the ring, the other perpendicular to it -kasayutsya annular conductor at points on opposite ends of a diameter. The strength of the current in the conductors 10 and 20 A. Determine the tension in the center of the ring conductor at a randomly selected direction of the currents. The decision to clarify the drawing.

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
