A pair of parallel horizontal conducting rails of negligible

A pair of parallel horizontal conducting rails of negligible resistance shorted at one end is fixed on a table The distance between the rails is L A conducting massless rod of resistance R can slide on the rails frictionlessly The rod is tied to a massless string which passes over pulley fixed to the edge of the table
