The temperature of a body is increased by `50%`. The amount of radiation emitted by it would be nearly

Options

A. Increase by `400%`
B. Decrease by `400%`
C. Decrease by `50%`
D. Increase by `50 %`

Explanation

`E_(1)alphaT^(4)`
`E_(2)a(T+T//2)^(4)`
`E_(2)=((3)/(2))^(4)(E_(1))`
`DeltaE%=(E_(2)-E_(1))/(E_(1))xx100`
`=[(11)/(16)-1]xx100= ~~400`
