$01.$ Two horizontal straight and parallel wires $65\mathrm{.}0$ m long and $9\mathrm{.}75$ cm apart each carry $27\mathrm{.}5$ A of current directed toward the north. The two wires are at the same height so that one wire is further east than the other $($by $9\mathrm{.}75$ cm$).$

a$.)$ What is the magnitude and direction of the force on the eastern$-$most wire by the western$-$most wire?

b$.)$ What is the magnitude and direction of the force on the western$-$most wire by the eastern$-$most wire?

c$.)$ Are the forces on each of the two wires by the other wire attractive or repulsive?
