There long straight wires A, B and C are carrying current as shown figure. Then the resultant force on B is directed
(a) Towards A
(b) Towards C
(c) Perpendicular to the plane of paper and outward
(d) Perpendicular to the plane of paper and inward
(b) , so force on B due to C will be greater than that due A. Hence net force on B acts towards C.
