Question

A conducting rod of mass m and length L is connected by two identical springs as shown in the figure. Initially the system is in equilibrium. A uniform magnetic field of magnitude B directed pependicular to the plane of the paper outwards also exists in the region. If a current l is switched on that passes from P to Q through the rod. Further maximum elongation in the spring is [mg = Bil]
