    Two very thin metallic wires placed along X and Y-axis carry equal currents as shown here. AB and CD are lines at \[45{}^\circ \] with the axes with origin of axes at O. The magnetic field will be zero on the line  [MP PMT 1995; CBSE PMT 1996]

    A)            AB

    B)            CD

    C)            Segment OB only of line AB

    D)            Segment OC only of line CD

    Correct Answer: A

    Solution :

               Every point on line AB will be equidistant from X and Y-axis. So magnetic field at every point on line AB due to wire 1 along X-axis is equal in magnitude but opposite in direction to the magnetic field due to wire along Y-axis. Hence \[{{B}_{net}}\]on \[AB=0\]
