The sun delivers `10^(3)W//m^(2)` of electromagnetic flux to the earth's surface. The total power that is incident on a roof of dimensions `8mxx20m` is `1.6xx10^(5)W`, the radiation force on the roof will be-

A

`3.33xx10^(-5)N`

B

`5.33xx10^(-4)N`

C

`7.33xx10^(-3)N`

D

`9.33xx10^(-2)N`

Text Solution

Verified by Experts

The correct Answer is:
B
`F=PA=(SA)/(c )=(1.6xx10^(5))/(3xx10^(8))=5.33xx10^(-4)N`
(or) `F="total power"//"veloctiy of light"`
