Magnetic field due to currentHard
Question
Two very long, straight, parallel wires carry currents I and -I respectively. The distance between the wires is d. At a certain instant of time, a point charge q is at a point equidistant from the two wires, in the plane of the wires. Its instantaneous velocity 
is perpendicular to this plane. The magnitude of the force due to magnetic field acting on the charge at this instant is :-
