Question

The figure below gives the potential energy U of a magnetic dipole in an external magnetic field , as a function of angle between the directions of and the dipole moment. The vertical axis scale is set by Us = 2.0 10-4 J. The dipole can be rotated about an axle with negligible friction so as to change . Counterclockwise rotation from = 0 yields positive values of , and clockwise rotations yield negative values. The dipole is to be released at angle = 0 with a rotational kinetic energy of 5.74 10-4 J, so that it rotates counterclockwise. To what maximum value of will it rotate? (What value is the turning point in the potential well of the figure?) 1
