A segment of a high-voltage power line

 A segment of a high-voltage power line is 250 m long and carries 110 A current. At this particular location, Earth's magnetic field is directed toward the North, at an angle of 72 degrees below horizontal (i.e., downward into the ground at an angle). The field is uniform and has a magnitude of 0.59 Gauss. If current in the power line is flowing horizontally toward the east, what is the magnitude of the magnetic force on the wire?

Hint: Think carefully about how to draw a diagram that will allow you to visualize all the relevant vectors.

Units: 1 Gauss is equal to 10-4 T. As usual, enter all numerical answers with three significant digits.
