A square, conducting, wire loop of side L, total mass m, and total resistance R. initially lies in the horizontal xy-plane, with corners at (x, y, z) = (0, 0, 0), (0, L, 0), (L, 0, 0), and (L, L, 0). There is a uniform, upward magnetic field B=Bk in the space within and around the loop. The side of the loop that extends from (0, 0, 0) to (L, 0, 0) is held in place on the x-axis; the rest of the loop is free to pivot around this axis. When the loop is released, it begins to rotate due to the gravitational torque. Part A Find the net torque that acts on the loop when it has rotated through an angle from its original orientation and is rotating downward at an angular speed w Assume that the direction of the gravitational torque is positive. Express your answer in terms of some or all of the variables L, m, R, B, 6, w, magnetic constant, and acceleration due to gravity g. IVE ΑΣΦ + ?
