(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The acceleration due to gravity is given by Newton's universal law of gravitation as:

g=(GM)/r^2

Derive analgebraicexpression for the error in gravity (Eg) due to the uncertainty in r. You may assume that the errors in G & M = 0; (EG & EM = 0)

Let E=error in for internet purposes

2. Relevant equations

g=(GM)/r^2

3. The attempt at a solution

r^2=(GM)/g

r=(GM/g)^(1/2)

r=[(GM)^(1/2)]/[g^1/2]

This is calculus, i can't see a classical algebraic way of doing this..

any help plz?
