A conducting rod, with a resistor of resistance R. is pulled with constant speed v on a smooth conducting rail as shown in figure. A constant magnetic field vecB is directed into the page. If the speed of the bar is doubled, by what factor does the rate of heat dissipation across the resistance R change?
