Question

5. + 0/1 points Previous Answers My Notes Two long, parallel wires carry currents of I, = 3.30 A and 1, = 4.80 A in the directions indicated in the figure below, where d = 16.0 cm. (Take the positive x direction to be to the right.) PLEASE COMPLETE ONLY PART (b) FOR CREDIT. PART (a) CAN BE LEFT UNDONE. 10-------01, (a) PLEASE SKIP THIS PART. PART (a) IS WORTH ZERO POINTS! Find the magnitude and direction of the magnetic field at a point midway between the wires. magnitude direction counterclockwise from the +x axis (b) Find the magnitude and direction of the magnetic field at point P, located d = 16.0 cm above the wire carrying the 4.80-A current. 9.381759463 x magnitude Your response differs from the correct answer by more than 10%. Double check your calculations. ut 71.886 direction Your response differs from the correct answer by more than 10%. Double check your calculations. counterclockwise from the +x axis

I'm very stuck on this, any help would be appreciated!
