Dear Student ,
Here in this case ,
Effective area =2RH2  where, triangle of base 2R and height H
Radiation pressure=IntensitySpeed=ICForce=P+A=IC×RH
Option (D) is correct
Regards

7. The radiation force experienced by a body exposed to radiation of intensity I ( assuming surface of body to be perfectly absorbing) is A πR 2 I c B πRHI c C I R H 2 c D I R H c

7. The radiation force experienced by a body exposed to radiation of intensity I ( assuming surface of body to be perfectly absorbing) is

$(A) \frac{{πR}^{2} I}{c} (B) \frac{πRHI}{c} (C) \frac{I R H}{2 c} (D) \frac{I R H}{c}$
