Question

Two long current-carrying wires are placed in a Cartesian coordinate system as shown.
Wire 1 has a current of 175 mA and is into the page at coordinate (-2.75 cm, 0) whereas
wire 2 has a current 825 mA and is out of the page at coordinate (0, 3.00 cm).
a. Calculate the net magnetic field (in i, j, k vector form) due to the two wires
generated at point P at coordinate (3.00 cm, 0). 
b. If a third long current-carrying wire is placed at point P with its current equal to
455 mA and into the page, calculate the magnitude of the net force per unit length
acting on the third wire due to the first two wires
