A rigid wire loop of square shape having side of length L and resistance R is moving along the x-axis with a constant velocity `v_(0)` in the plane of the paper. At t=0 , the right edge of the loop enters a region of length 3L where there is a uniform magnetic field `B_(0)` into the plane of the paper, as shown in the figure. For sufficiently large `v_(0)`, the loop eventually crosses the region. Let x be the location of the right edge of the loop. Let `v(x),I_(x) and F_(x)` represent the velocity of the loop, current in the loop, and force on the loop, respectively, as a function of x. Counter-clockwise curren is taken as positive.
