A brilliant arc lamp delivers a liuminous flux of 100 W to a 1cm² absorber. The force due to radiation pressure is.

a. 3.3 X 10^-4 N

b. 16.5 X 10^-7 N

c. 3.3 X 10^-6 N

d. 3.3 X 10^-7 N

Plz solve step by step....!~

the answer what i am getting is 3.3 x 10 ^-7 N

this is how i got it .....we r asked to find the force due to radiation pressure .                             what is radiation  pressure? pressure due too the radiation given ... so radiation pressure is to b calculated from which force can b calculated....                                                                   radiation pressure     =  flux density / speed of light

           flux density =   flux/ area    =  100/10 ^-4    W/ m²   =  10 ⁶ W / m²  

    radiation pressure =   10 ⁶ / 3 x 10⁸  W s / m³

   ^{force                 =  pressure x area}

                          = 3.3 x 10 ^-3  x 10 ^-4 W s / m³  x m ²

                         =  3.3 x 10^-7 W s / m

                          = 3.3 x 10 ^-7  N

rate if correct :)`
