A cylindrical metallic rod is in thermal contact with two reservoirs of heat, its two ends conduct an amount of heat Q in time t in steady state. If this rod is replaced by another rod of same material having double radius of the first rod. The amount of heat conducted by the new rod in same time in steady state will be
