MHT CET Physics question
A black body at a temperature of 227℃ radiates heat energy at the rate of 5 cal/cm²-second. At a temperature of 727℃, the rate of heat radiated per unit area in cal/cm² will be
Answer: (A)
Solution
Rate : ; 160, 250 and 500 are not 16 times 5. Hence the correct option is (a).
