Two long straight conducting wires are parallel with thez-axis. The first wire passes through the origin andcarries a current of 10 A in the +z direction. The secondwire passes through the point x = 2.0 m, y = 2.0 m and carriesa current of 5.0 A in the – z direction. Calculatethe force per unit length that one conductor exerts on theother. State whether this force is repulsive orattractive. Given Equation: F/l =0I1I2 /2d Two long straight conducting wires are parallel with thez-axis.

Explanation / Answer
the force per unit length that one conductor exerts on theother F=B*I*L=0*I1/(2r)*I2*1m r=22 cm =>F=3.5*10-5 N bu using the right hand rules=> repulsive forces
