Answer 1

Answer:

A and B are sections of two long parallel wires placed perpendicular to the plane of the paper. They carry current of 5A and 10A respectively in the directions indicated in the figure. If the separation between them is 3m, the zero of the magnetic field in the plane of the paper is at a point :
