If the distance to the center of the earth increases by 2% the inverse square law dictates the force of gravity decreases by 4% (approximately) so choice A,
Explanation:
OK, sure Sana. The way I understand the question I guess the original amount of gravitational force on the satellite on the surface of the earth, its weight, is
where
Once it's launched, the distance from the satellite to the center of the earth we're told is
That's about
