A long straight wire carries a 40.0 A current in the +x direction. At a particular instant, an electron moving at 1.0 × 107 m/s in the +y direction is 0.10 m from the wire. The charge on the electron is -1.6 × 10-19 C. What is the force on the electron at this instant? 
A) 1.3 × 10-16 N in the +x direction
B) 1.3 × 10-16 N in the -x direction
C) 6.5 × 10-10 N in the +y direction
D) 6.5 × 10-10 N in the -y direction
E) 6.5 × 10-16 N in the -y direction
