Transcribed Image Text:
A straight wire of mass 40 g and length 5.0 cm is suspended from two identical springs that, in turn, form a closed circuit (see the figure). The springs stretch a distance of 0.5 cm under the weight of the wire. The circuit has a total resistance of 12 2. When a magnetic field directed out of the page (indicated by the dots in the figure) is turned on, the springs are observed to stretch an additional 0.30 cm.
