Three distinct current wires intersect a finite rectangular plane ABCD. The current is left wire and the loop is `l_(1)` . The direction of current in left most wire and righy most loop is downards as shown in the figure. The current `l_(2)`through middle wire is adjusted so that the path integal of the total magnetic field along the perimeter of the rectangle is zero , that is ,`underset(ABCDA)ointvecB.dvecs=0` then the current `I_(2)` is
