Four very long straight wires carry equal electric currents in the +z direction. They intersect the x-y plane at (x,y)=(-a,0),(a,0),(0,a),(0,-a).The magnetic force exerted on the wire at position (-a,0) is along |

Answer» `+y` `because""|vecF_(1)|=|vecF_(2)|` `therefore` Their resultant will be ALONG `vecF_(3)` i.e.X-axis So net force on WIRE sis along `+X` DIRECTION |
