Q 1647156983.     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 sufficient 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 current is taken as positive.
