If the temperature of body is increased ...

If the temperature of body is increased by `10%` the percentage increase in the emitted radiation will be :

A

`46%`

B

`40%`

C

`30%`

D

`80%`

Text Solution

Verified by Experts

The correct Answer is:
A
Here `EpropT^(4)`
`:.(E_(2)-E_(1))/(E_(1))xx100=(T_(2)^(4)-T_(1)^(4))/(T_(1)^(4))xx100`
`((110)^(4)-(100)^(4))/((100)^(4))xx100`
`=[(1.1)^(4)-1]xx100`
`=(1.46-1)xx100=46%`
Correct choice is (a).
