A conducting rod of length 1 m negligible resistance slides without friction on two parallel vertical conducting rails connected at the top through a resistor of resistance R The rails are also of negligible resistance A uniform magnetic field Bo exists perpendicular to the plane of the rails pointing inward After a long time the heat dissipated in the resistor per second is 1 m g 2B 2R 2m g R www R B 2 f ilksi 98 filb m g R B 1 m g
