Four very long straight wires carry equal electric currents in the + z direction. They intersect the x-y plane at (x, y) = (– a, 0), (0, a) (a, 0) and (0, – a). The magnetic force exerted on the wire at position (– a, 0) is along–
Text Solution
Verified by ExpertsThe correct answer is:
C
Their resultant will be along 
i.e.X-axis
So net force on wire sis along 
direction
