A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.12 m and a mass of 0.005 kg. A uniform magnetic field of magnitude 0.055 T is directed from the ceiling to the floor. When a current of 1-34 A exists in the wire, the wire swings upward and, at equilibrium, makes an angle op with respect to the vertical, as the drawing shows. Find (a) the angle and (b) the tension in each of the two strings. N S
