2. [-/1 PUNTOS] DETALLES SERPSE10 28.5.OP.022.MI. MIS NOTAS PREGUNTA A TU PROFESOR An eight-turn coil encloses an elliptical area having a major axis of 40.0 cm and a minor axis of 30.0 cm (see figure). The coil lies in the plane of the page and has a 6.15-A current flowing clockwise around it. If the coil is in a uniform magnetic field of 2.02 x 104 T directed toward the left of the page, what is the magnitude of the torque on the coil? Hint: The area of an ellipse is A = nab, where a and b are, respectively, the semimajor and semiminor axes of the ellipse. N.m 40.0 cm -30.0 cm-|
