A long straight horizontal cable carries a current of `2.5amp`. In the direction `10^@` south of west to `10^@` north of east, figure. The magnetic meridian of the place happens to be `10^@` west of the geographic meridian. The earth's magnetic field at the location is `0.33G` and the angle of dip is zero. Locate the line of neutral points (Ignore the thickness of the cable). [At neutral points, magnetic fied due to a current cable is equal and opposite to the horizontal component of earth's magnetic field.]
