IMPOSSIBLE SAT II QUESTION (750+ Physics SAT II ONLY)

<p>Hi. I have a question on the June 2005 Physics NYS Regents. </p>

<p>A satellite weighs 200 newtons on the surface of Earth. What is its weight at a distance of one Earth radius above the surface of Earth? </p>

<p>Can someone help me with a detailed explaination? Thanks!!</p>

<p>50 newtons. if you double the distance, the gravitational force is quartered.</p>

<p>^ yep. the gravitational force equation has a d^2 for the denominator. therefore (2r)^2 distance means the force divided by 4.</p>

<p>Just use Newton's Law of Gravitation: F = Gm1m2/r^2</p>

<p>wow...this is a really sad thread...somebody please delete or close it</p>

<p>Impossible?! This is only a regents question. LOL.</p>
