At the distance of the earth from the sun, the pressureexerted by sunlight is about 10-5 Pa. How muchforce does this pressure exert on a 10 m2 array of solarcells on a satellite when the array is perpendicular to thedirection of the sunlight? If the satellite has a mass of 200kg, what acceleration does this force give it?
