How far from Earth must a space probe be along a line toward the Sun so that the Sun's gravitational pull on the probe balances the Earth's pull?
I'm actually just confused as to how to set this up. I know that I need to consider d being the distance from the Earth to the sun and r being the distance from the Earth to the probe. And use (d-r). Any help as to how I should set this up would be greatly appreciated. Part of what I'm confused with is that when referring to pull I'm thinking that is a force right. I'm completely lost as to how to start this one.
