As shown in the figure, a conducting rod with a length of 0.82 m is placed on a horizontal frictionless surface and attached to a power supply by two springs, each with a spring constant of 75 N/m. The springs are initially at their equilibrium length and are in a region where there is a uniform magnetic field of 0.18 T that is perpendicular to the frictionless surface when the power supply supplies a current that causes the wire to move in such a direction that the two springs are stretched.
