Earth orbiting satellite has solar energy collecting panel with total area 5 ~m ^2 . If solar radiations are perpendicular and completely absorbed, the average force associated with the radiation pressure is
Options
- A2.33 10⁻³ ~N
- B2.33 10⁻⁴ ~N
- C2.33 10⁻⁵ ~N
- D2.33 10⁻⁶ ~N
Correct answer
C. 2.33 10⁻⁵ ~N
Step-by-step solution
aligned As, power & = solar constant area & = (1.4 10^3 ) 5 ~W aligned aligned Force & = solar constant area speed of light & = 1.4 10^3 5 3 10^8 =2.33 10⁻⁵ ~N aligned
