(b) An infinitely long wire carries a current I = 10 A as shown in Figure 2. An electron at a perpendicular distance of 3.0 cm away from the wire moves in a direction parallel to the wire and opposite to the direction of the current. Given that the velocity of the electron v = 2 x 107 m/s, determine the magnitude and direction of the magnetic force acting on the electron. 3.0 cm Figure 2 (13 Marks)
