Question $14[6$ pts$]$ Circle the correct response. Two circuits in which a conducting bar is forced to slide with the same speed, $v,$ along a $U-$shaped wire. Both circuits are placed in the same constant uniform magnetic field vec$(B).$ The length of the parallel side of the wire is $L$ for circuit $1,$ and $\frac{L}{2}$ for circuit $2.$
