Two bodies hae temperatures as `227^(@)C` and `727^(@)C` ratio of heat radiated by them will be

A

`1:4`

B

`1:16`

C

`16:1`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:
B
Ratio of heat radiated by the two
bodies, `(E_(1))/(E_(2))=(T_(1)^(4))/(T_(2)^(4))`
here, `T_(1)=500K`
`T_(2)=1000K`
`therefore(E_(1))/(E_(2))=((500)/(1000))^(4)=(1)/(16)`
