A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.10 m anda mass of 0.008 kg. A uniform magnetic field ofmagnitude 0.075 T is directed from the ceiling to the floor. When a current of I = 26 A exists inthe wire, the wire swings upward and, at equilibrium, makes anangle φ with respect to the vertical, as the drawingshows. Find (a) the angle and (b)the tension in each of the two strings.
