A Coil of Radius R = 5 Cm Lies Inside $\theta$

A coil of radius R = 5 cm lies inside a long solenoid that carries a current I₁ = 10 A and has 800 turns per meter. The coil carries a current I₂ = 4 A and the normal of the plane of the coil is at an angle $\theta$ = 30º with the axis of the solenoid. The magnitude of the torque on the coil is

A) 1.57 × 10^-4 N m.
B) 2.74 × 10^-4 N m.
C) 5.03 × 10^-5 N m.
D) 3.16 × 10^-4 N m.
E) None of the above.
