Two long, straight, parallel wires are 1 .00 in apart. The wire on the left carries a current I1 of 6.00 A into the plane of the paper.
(a.) What must the magnitude and direction of the current I2 be for the net field at point P to be zero?
(b.) Then what are the magnitude and direction of the riel field al Q?
(c.) Then what is the magnitude of the net field at S?
(d.) At what angle from the horizontal is the net field at S?
