A Straight Wire Carries a Current of 40 a in a Uniform

A straight wire carries a current of 40 A in a uniform magnetic field (magnitude = 80 mT) .If the force per unit length on this wire is 2.0 N/m,determine the angle between the wire and the magnetic field.

A) either 39 $\degree$ or 141 $\degree$
B) either 25 $\degree$ or 155 $\degree$
C) either 70 $\degree$ or 110 $\degree$
D) either 42 $\degree$ or 138 $\degree$
E) either 65 $\degree$ or 115 $\degree$
