1. The problem statement, all variables and given/known data My physics teacher today said that the earth exerts the same amount of gravitational pull on sun;as the sun exerts on the earth. Is this really true? 2. Relevant equations There is no equation. 3. The attempt at a solution I am very confused with this. How can the earth's gravitational pull equal that of a massive body like the sun? Can somebody explain this to me please?
