A body radiates heat at the rate of 50 J/s at 300 K. when the same body is at 600 K then its rate of radiation of heat will be

A

100 J/s

B

200 J/s

C

400 J/s

D

800 J/s

Text Solution

Verified by Experts

The correct Answer is:
D
`(R_(2))/(R_(1))=((T_(2))/(T_(1)))^(4)=((600)/(300))^(4)=16`
`R_(2)=16xx50=800J//s`
