1)Which describes the 1D gravitational force in this figure. (+x is to the right.)
2)In moving the little mass m from x1 to infinity the force of gravity does _____________ work.
I added an attachment for the figure
The Attempt at a Solution
I only have one attempt at it so I want to make sure my logic is right.
1) I think the answer is Fgrav=−GMmx2 because the little mass is going away from the gravitational pull
2) Because of my explanation in #1, I believe the answer is negative
