Question

The sun delivers 103 W / m 2 of electromagnetic flux to the earth's surface. the radiation force on the roof will be (A) 8.53 × 10-5 N (B) 2.3 × 10-3 N (C) 1.33 × 10-3 N (D) 5.33 × 10-4 N

Force of radiation =( text Power /c) =(1.6 × 105/3 × 108) =5.32 × 10-4 N

Q. The sun delivers $1 0^{3} W / m^{2}$ of electromagnetic flux to the earth's surface. the radiation force on the roof will be

$8.53 \times 1 0^{- 5} N$

$2.3 \times 1 0^{- 3} N$

$1.33 \times 1 0^{- 3} N$

$5.33 \times 1 0^{- 4} N$

Force of radiation $= \frac{Power}{c}$
$= \frac{1.6 \times 1 0 ^{5}}{3 \times 1 0 ^{8}}$
$= 5.32 \times 1 0^{- 4} N$

Q. The sun delivers 103W/m2 of electromagnetic flux to the earth's surface. the radiation force on the roof will be

8.53×10−5N

2.3×10−3N

1.33×10−3N

5.33×10−4N
