A long rod has one end at 0c ,other end at high temperature . The coefficient of thermalconductivity varies with distance from the low temperature end as k = k0( 1 + ax ) , where k0 = 100sI unit and a= 1/m , At what distance from the 1st end the temperature will be 100C ? Area = 1/10000cgs , and rate of heat conduction is 1watt. a) 2.7m b) 1.7m c) 3m d) 1.5m
