A body with surface area (A), temperature (T) and emissivity (e) = 0.6 is kept inside a spherical black body. What will be the maximum energy radiated ?
[`sigma` is Stefan's constant]

A

`0.60 sigma AT^4`

B

`1.00 sigma AT^4`

C

`0.80 sigma AT^4`

D

`0.40 sigma AT^4`

Text Solution

Verified by Experts

The correct Answer is:
B
Body is placed within hollow enclosure and in this case its behaviour will be like a black body. Rate of radiation is `e sigma A T^4` and for this case e = 1 (black body).
