Question 7 10 pts Two long, straight wires are perpendicular to the plane of the paper and at a distance 0.2 m from each other, as shown in the gure. The wires carry currents of I1 = 1.1 Aand '2 = 4.7 A in the direction indicated (out of the page). Find the magnitude and direction of the magnetic eld (in pT) at a point A midway between the wires. You need to indicate the direction with a positive or a negative value for the magnetic eld. Keep in mind that a vector is positive if directed to the right and negative if directed to the left on the x axis and it is positive if directed up and negative if directed down on the y axis. Your answer should be a number with two decimal places, do not include the unit. Question 8 10 pts The force per meter between the two wires of a jumper cable being used to start a stalled car is 0.257 N/m. What is the current in the wires, given they are separated by 4 cm? You should round your answer to the nearest integer. Do not indicate unit
