The figure below is a top view of a rectangular thin wire loop that moves with velocity vo on a horizontal table. The friction against the table is negligible so that this motion would continue practically with the same velocity if not for crossing the boundary of the region of the uniform magnetic field B=3074 G, also shown in the figure. From our discussions in class, you know that this crossing is accompanied by the slowing down of the loop motion facilitated by the phenomenon of induction. In fact, while crossing the boundary, the loop's velocity v(t) would be changing with time t according to the equation dv - у dt т" just as if the loop were experiencing the friction force with some effective parameter t. The geometrical dimensions of the loop are given: a=10 cm, b=29.5 cm, as well as its total resistance R=0.428 I and mass m=5 g. b ХХХХХХХХХХ ХХХХ ХХХХ Ххх в ХХХХ ХХХХХХХХХХХХХХХХ ХХХХХХХХХХХХХХХХ xxxx ХХХХХ ХХХХ xxx XXX ХХХХ ХХХХХ а R M vo Understandably, if the velocity vo is "too low", the loop would stop before completely crossing the boundary of the magnetic field region.

Would you be able to type this answer out? When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate....
