A horizontal, long current-carrying wire is hanging from a vertical thread. The current is oriented into the plane of Fig. 27-10 shown above. A uniform magnetic field B = 0.4 T is applied along the negative y-axis and the wire is pulled and angle 8 away from the vertical by a magnetic force. The wire has a length L = 80 cm, a mass m = 50 g and carries a current I = 0.3k What is the value of the angle ??
