Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

Ch5_3 #2
See Ch 5 Sheet 26 and the algebraic equation under "Note" in Ch5_3 #1. What do you set g' equal to ? Solve for h.

GM/(R+h)^2 = .5* GM/R^2
2GM/(R+h)^2 = GM/R^2
2GM=(GM/R^2)(R+h)^2
2= (R+h)^2 / R^2
2R^2 = (R+h)^2
sqrt 2 * R = R+h
h= R(sqrt2 -1)
