If the temperature of the hot body is increased by `50%` the amount of radiation emitted is increased by nearly :

A

`50%`

B

`225%`

C

`250%`

D

`400%`

Text Solution

Verified by Experts

The correct Answer is:
D
`(E_(2))/(E_(1))=((150)/(100))^(4)=5*06`
`rArr" "(E_(2))/(E_(1))-1=5*06-1`
`(E_(2)-E_(1))/(E_(1))xx100=4*06xx100=400%`
Thus correct choice is (d).
