In the figure below, a long rectangular conducting loop, of width L = 8 cm, resistance R = 10 N, and mass m = 0.09 kg, is hung in a horizontal,
uniform magnetic field of 3.5 T that is directed into the page and that exists only above the line aa. The loop is then dropped and it falls at
constant velocity. Find that constant velocity.
