In the figure shown a current $I_1$ is established in the long straight wire $AB$.Another wire $CD$ carrying current $I_2$ is placed in the plane of the paper. The line joining the ends of this wire is perpendicular to the wire $AB$. The force on the wire $CD$ is:
  • A
    zero
  • B
    towards left
  • C
    directed upwards
  • D
    none of these
