Consider two very long conducting parallel wires carry currents in opposite directions such that one is triple of the other. The distance between wires is 30 cm. The magnetic field at points on a line between the wires, and at a distance of 5 cm from the wire carrying the smaller current, is 2.5×10-5 T. a) Draw a diagram of the situation. Assume the wires are placed in the x-direction. Draw the direction of the magnetic field at points on that line. b) What are the currents in the wires? c) If an electron (e= 1.6×10-19 C , m=9.11×10-31 kg), at a given instant, passes at a point on that line and is moving at an angle of 45o to the direction of the magnetic field with a speed of 2.5×106 m/s, what would be its initial acceleration?
