Assume There Is a Current of 3

Multiple Choice

Assume there is a current of 3.0 A traveling clockwise in a loop around this piece of paper (which is approximately 22 cm wide and 28 cm long) .There is an infinitely long wire that runs parallel to the top edge of the paper that carries a current of 5.0 A.If the distance between the top edge and the wire is 50 cm find the magnitude of the torque on the current loop.

A) zero
B) 2.4 10^-7 N ^. m
C) 2.9 10^-7 N ^. m
D) 3.0 10^-7 N ^. m
