Question 21 of 21 > A 300-turn wire loop with a 5.0 cm radius is connected to a 0.20-kg pulley by a lightweight rod. The pulley, which has a radius of 3.1 cm, is attached to a 4.1-kg block by a massless Macmillan Learning rope, as shown in the figure. The loop is in a 0.75-T magnetic field. When no current flows through the wire loop, the plane S of the loop is parallel to the magnetic field, and the block N attached to the pulley just touches the ground. However, when a 0.85-A current flows through the loop, magnetic forces cause the loop to rotate, which lifts the block off the ground. Calculate the equilibrium angle 0 of plane of the loop relative to the magnetic field. To what height y off the ground is the block lifted? m hp
