1. A large power cable carries I = 200 A in a straight line East-West for L = 100 m to a device and
returns the same current to the power source in the opposite direction. The return path is also
straight and runs parallel to the first path directly above it.

The cable is made of copper with resistivity po = 17.2×10 Qm and mass density pcu = 8960 kg/m³.
The cable has a diameter of d = 8.00 cm.
a) What force (magnitude and direction) is exerted on the outgoing (+) cable by the magnetic
field of the earth? Use a value of B = 40.0 μT for the earth's field, and assume it points,
straight north. [1 point]
b) Is there a force between the two cables, and is it attractive or repulsive? Briefly explain your
answer. [0.5 points]
c) How far apart should the two cables be kept so that the force between them is less than 1.0 N?
[1 point]
d) Suppose the cables are set apart at the distance you got in c). How much torque is exerted on
the…
