Question

Radiation force experienced by a spherical body exposed to radiation of intensity
1WmI(assuming
radius 1mR, body be perfectly absorbing) is
​

Answer 1

Answer:

Hope it helps you!

Explanation:

Here in this case,

Effective area A=

2

2RH

where triangle of base 2R and height H

Radiation pressure P=

Speed

Intensity

=

C

I

And hence Radiation Force=P×A=

C

I

×RH

⟹F=

C

IHR
