A long straight wire on the z-axis carries a current of 6.0 A in the positive direction. A circular loop in the xy-plane, of radius 10 cm, carries a 1.0-A current, as shown in the figure. Point P, at the center of the loop, is 25 cm from the z-axis. An electron is projected from P with a velocity of 1.0 × 106 m/s in the negative x-direction. What is the y component of the force on the electron?
A) zero
B) -1.0 x 10^-18 N
C) +2.0 x 10^-18 N
D) -2.0 x 10^-18 N
E) +1.0 x 10^-18 N
Answer: B) -1.0 x 10^-18 N
