Question

Please help me with this sum correct option is D

The radiation force experienced by body exposed to radiation of
intensity I, assuming surface of body to be perfectly absorbing is
:

a) a )   π R 2 I c          
              b )   π R
H I c                
        c )   I R H 2 c    
                  d )
  I R H c

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

Please help me with this sum correct option is D The radiation force experienced by body exposed to radiation of intensity I, assuming surface of body to be perfectly absorbing is : a) a ) π R 2 I c b ) π R H I c c ) I R H 2 c d ) I R H c

Please help me with this sum correct option is D

The radiation force experienced by body exposed to radiation of intensity I, assuming surface of body to be perfectly absorbing is :

a) $a) \frac{π R^{2} I}{c} b) \frac{π R H I}{c} c) \frac{I R H}{2 c} d) \frac{I R H}{c}$
