In a two-level system, the relative level population (lower: upper) was found to be 0.25 : 0.5. The spacing between the levels is 100 k Joules, where k is magnitude of the Boltzmann constant. The etfective temperature of the system is (a)-50K (b)-100 In(2) K (b) -100/In(2) K (d) None of the above Sand to he half and a sixth as populated
