At a site where the earth's magnetic field has a magnitude of 0.55 gauss (where 1 gauss = 1.00 10-4 t) and points to the north, 68° below the horizontal, a high-voltage power line 152 m in length carries a current of 120 a. determine the magnitude and direction of the magnetic force exerted on this wire, if the orientation of the wire and hence the current is as follows.
