Homework Statement
The acceleration due to gravity is given by Newton's universal law of gravitation as:
g=(GM)/r^2
Derive an algebraic expression 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
Homework Equations
g=(GM)/r^2
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 please?
