1. The problem statement, all variables and given/known data The mass of the moon is 7.35x10^22 kg. At some point between Earth and the Moon, the force of Earth's gravitational attraction on an object is canceled by the Moon's force of gravitational attraction. If the distance between Earth and the Moon (centre to centre) is 3.84x10^5, calculate where this will occur, relative to Earth 2. Relevant equations Fg = (G x m1 x m2) / r^2 3. The attempt at a solution I know you have to make the Earth's gravitational attraction equal the Moon's gravitational attraction (by putting the preceding equation equal to each other). But i dont know where to plug in the 3.84x10^5. Am i looking for the Moon's r? or Earth's r? im just not too sure about how to go about solving this?
