Three long parallel wires

Three long parallel wires are 3.8 cm  {\rm cm} from one another. (Looking along them, they are at three corners of an equilateral triangle.) The current in each wire is 9.50A  A , but its direction in wire M  {\rm M} is opposite to that in wires N  {\rm N} and P (see the figure (Figure 1) ).

1)Determine the magnitude of the magnetic force per unit length on wire M due to the other two.

2)Determine the angle of the magnetic force per unit length on wire M due to the other two.

3)Determine the magnitude of the magnetic force per unit length on wire N due to the other two.

4)Determine angle of the magnetic force per unit length on wire N due to the other two.

5)Determine the magnitude of the magnetic force per unit length on wire P due to the other two.

6)Determine the angle of the magnetic force per unit length on wire P due to the other two.
