Earth orbiting satellite has solar energy collecting panel with total area 5m^2. If solar radiation are perpendicular and completely absorbed

Question

Earth orbiting satellite has solar energy collecting panel with total area 5 m2. If solar radiations are perpendicular and completely absorbed, the average force associated with the radiation pressure is (solar constant = 1.4 kW m-2)

(a) 2.33 x 10-3 N

(b) 2.33 x 10-4 N

(c) 2.33 x 10-5 N

(d) 2.33 x 10-6 N

Answer 1

The correct option is (C) 2.33 x 10-5 N.

Explanation:

Power = I x Area = 1.4 x 103 x 5 and

F = Power/c = (1.4 x 103 x 5)/ (3 x 108) = 2.33 x 10-5 N
